Xpra: Ticket #1327: screen doesn't fit in Fullscreen mode

Bottom part of the screen is cut off in the fullscreen mode Image http://i.imgur.com/R13084A.png

I tried running server (in docker) with http://packages.ubuntu.com/yakkety/xpra

and https://www.xpra.org/dists/xenial/main/binary-amd64/xpra_0.17.5-r13455-2_amd64.deb both have this bug. This version http://packages.ubuntu.com/xenial/xpra works fine

At the client I tried http://packages.ubuntu.com/xenial/xpra and the one from the xpra repo.

It's really not clear to me what the problem is, the picture is too blurry.

Please include the exact commands that you used at both ends. (edit: just saw the report zip)

Thank You for responding so fast!

This is how it works with server xpra v0.15.8 | client xpra v0.17.5 http://i.imgur.com/KhN8gxW.png (all is ok)

These warnings look ominous: Uh-oh, our size doesn't fit window sizing constraints:.... Which application can I use to reproduce this bug? (package name? some kind of X11 version of emacs?)

Can you run both the client and server with "-d geometry"? The debug output should tell us more.

The

Uh-oh, our size doesn't fit window sizing constraints:....

happens when I run Ubuntu Xenial with its default xpra package in docker with any xpra client. xpra started with emacs as a child. On the client I have Ubuntu Xenial with Cinnamon desktop and NVIDIA drivers. This setup yields satisfying results http://i.imgur.com/KhN8gxW.png (my first example above) it has small black region at the bottom but I'm ok with it. I think the message appears when I try to resize the window.

But I don't have this message with the newest versions of xpra and the same client. Instead a have the bug :)

The problem is very likely to be the Uh-oh, our size doesn't fit window sizing constraints problem. Newer versions try harder to honour the window's size constraints. The black region at the bottom is the same symptom, just a different way of handling it.

This window has some very specific constraints:

{'minimum-size': (32, 34), 'gravity': 1, 'base-size': (24, 17), 'increment': (8, 17)}

Which we should be forwarding to the client window manager, which should be honouring those too. What desktop environment do you use? (and what is this application?)

Hm the problem may be specific to full screen Emacs. For example rhythmbox looks normal http://i.imgur.com/mbkZ3kD.png


Fri, 30 Sep 2016 20:15:30 GMT - JAremko:

it actually maybe not just a full screen problem. When I resize window Emacs sometimes fits and sometimes doesn't. May be the full screen dimension just happens to be one of the "broken ones" When I resize window (dragging with mouse) it resizes in steps (like if the size is rounded).And while it's jumping I can see black bar(for a split second) or it cuts off.

So I'm thinking. The full screen is a precise size, the window has to fit it precisely. The same with the half screen alignment http://i.imgur.com/8K4cEcE.png as you can see it's also broken.

Emacs devs helped me to figure it out. Setting frame-resize-pixelwise to t and rebooting Emacs or calling x-wm-set-size-hint solved the problem.

 frame-resize-pixelwise
If this option is nil, a frame’s size is usually rounded to a multiple
of the current values of that frame’s frame-char-height and frame-char-width whenever the frame is resized.
If this is non-nil, no rounding occurs, hence frame sizes can increase/decrease by one pixel.
Setting this variable usually causes the next resize operation to pass the corresponding size hints to the window manager.
This means that this variable should be set only in a user’s initial file; applications should never bind it temporarily.
The precise meaning of a value of nil for this option depends on the toolkit used.
Dragging the external border with the mouse is done character-wise provided
the window manager is willing to process the corresponding size hints.
Calling set-frame-size (see below) with arguments that do not specify
the frame size as an integer multiple of its character size, however,
may: be ignored, cause a rounding (GTK+), or be accepted (Lucid, Motif, MS-Windows).

Not sure if Xpra hast to handle cases like this differently, but if not feel free to close the ticket.

Thanks everyone'''


Tue, 11 Oct 2016 16:37:20 GMT - Thomas Esposito:

I'm seeing a similar problem with gnome-terminal version 2.31.3.

Here is a snippet of my log with "--debug=all". This is after I maximize the gnome-terminal window. My client is running Windows 7.

[36m2016-10-11 12:19:09,009 _process_configure_window([1, 0, 22, 1600, 1138, {}, 0, {}, False, 1, (1012, 331), ()]) old window geometry: (0, 22, 1601, 1149)
[36m2016-10-11 12:19:09,009 DesktopManager.configure_window(WindowModel(0x600005), 0, 22, 1600, 1138, 0)
[36m2016-10-11 12:19:09,009 _update_client_geometry: using owner=DesktopManager(1) (setup_done=True)
[36m2016-10-11 12:19:09,009 _do_update_client_geometry: allocated 1600x1138
[36m2016-10-11 12:19:09,009 _do_update_client_geometry: size({'minimum-size': (49, 61), 'gravity': 1, 'base-size': (17, 27), 'increment': (8, 17)})=1601x1149
[36m2016-10-11 12:19:09,009 Uh-oh, our size doesn't fit window sizing constraints: 1600x1138 vs 1601x1149
[36m2016-10-11 12:19:09,009 _do_update_client_geometry: position=0x22
[36m2016-10-11 12:19:09,009 updateprop(geometry, (0, 22, 1601, 1149)) unchanged

It seems pretty clear that although Windows 7 is maximizing to 1600x1138 (that's 1600x1200 resolution minus the Windows 7 taskbar and maximized window titlebar), xpra is picking the closest constrained size that is >= the size requested by Windows 7 and sending that the X11 application. In an earlier email you said that "the size increments should be forwarded to the client". Do you mean the xpra client running on Windows 7, or the X11 client app (i.e. gnome-terminal)?

I dug into the code a bit and it looks like this is all happening in a function named "calc_constrained_size()", but I'm not sure where it is being imported from. I don't know python...


Wed, 12 Oct 2016 07:39:43 GMT - Antoine Martin:

The size constraints are forwarded to the client, ie with "-d metadata" for an xterm:

set_size_constraints({'base-size': (19, 4), 'size': (499, 316), 'gravity': 1, 'increment': (6, 13), 'minimum-size': (25, 17)}, (6144, 6144))

So the client OS should honour the constraints set by the application.

calc_constrained_size is here: browser/xpra/trunk/src/xpra/x11/gtk2/gdk_bindings.pyx.


Wed, 12 Oct 2016 13:15:40 GMT - Thomas Esposito:

It looks like the end of this function, after the first call to gdk_window_constrain_size() (which rounds down), will actually round UP to the next size increment if the abs() between that and the original requested size is smaller. Why would you want to do this?

I'll try patching my install.


Wed, 12 Oct 2016 14:07:31 GMT - Thomas Esposito:

Removing the "round up" code seems to fix the issue. Although I agree this wouldn't be an issue at all if Win32 respected the size increments.

Interestingly, if I grab the corner of the window and drag to resize (while NOT maximized), the size increments DO obey the constraints. It is only when it's maximized that Win32 doesn't obey the constraints.

When I use gnome-terminal in Exceed TurboX VA, Win32 respects the constraints, even when maximized, and draws a window border around the right and bottom edge of the smaller-than-fully-maximized-window even when in the maximized state.

Win32 obviously supports the case where a window is logically maximized, but physically smaller. Maybe there is an extra bit of code necessary in the Win32 client in order to handle this corner case? Perhaps, there is a specific way to "force" the window to a particular size, even when in the maximized state?

Edit: Disregard this. gnome-terminal had multiple tabs open in Exceed and only 1 tab in xpra. Between the two, when the "round up" code is removed from xpra, there is NO difference in how the window is drawn.

Wed, 12 Oct 2016 14:11:39 GMT - Thomas Esposito:

Edit: Disregard this.

To be clear, when I say that removing the "round up" code fixes the issue, the window is padded out to the edges of the screen with blank white space. I don't get a "pretty" border like in Exceed TurboX VA.

Also, when using x2go, the result is nearly the same as xpra (with the "round up" code removed), EXCEPT that the window is padded out to the edges with blank BLACK space.


Sat, 15 Oct 2016 12:38:22 GMT - Thomas Esposito:

I'm waiting for feedback on this. Is this the same issue as the one originally reported? If not, I can open a new ticket.

I've found a solution, but I'm not sure if there would be unintended side effects of modifying calc_constrained_size to NOT round up the window size.


Fri, 21 Oct 2016 11:54:16 GMT - Antoine Martin: owner, status changed

This change to use rounding comes from here: ticket:976#comment:36. Resizing loops are very bad, we don't want those back!

New updates:

@thomase00: the colour of the padding area around the window may vary. What is the "pretty" border you would like to have instead? (maybe a small screenshot of that area would help)


Fri, 21 Oct 2016 13:04:24 GMT - Thomas Esposito:

Disregard my comments regarding the border. I was mistaken. With the round-up code removed from gdk_bindings.pyx, the window border is rendered similarly to comparable solutions.

It has occurred to me that there might be another possible solution. IF the calc_constrained_size() function is aware of whether or not the window has been maximized (I'm not sure if this is included in "hints"), it could skip the round-up ONLY in that particular case.

The changes you made in ui_client_base.py, desktop_server.py, server.py, seem to be totally unrelated to my particular issue. Do these changes relate to the original issue reported in the ticket?


Fri, 21 Oct 2016 13:09:24 GMT - Antoine Martin:

The other changes are needed to prevent the resizing loops. We cannot remove the rounding without those, see the link in comment:22 for details.

calc_constrained_size has no idea about maximized state, which is not part of the hints. The roundup causes other problems anyway (ie: try an xterm with desktop-scaling as per #1098), so getting rid of it is a good thing.

Can I close this ticket?


Fri, 21 Oct 2016 14:00:13 GMT - Thomas Esposito: status changed; resolution set
