Xpra beta - font artifacts, resize artifacts

[esarmien]

This is for the latest RPM BETA build of XPRA for Fedora:latest (25)

Problems:

• Resizing windows sometimes leaves artifacts, as shown in screenshots.
• Fonts letters sometimes overlap or become non-aliased, as shown in screenshots.
• Artifacts left over, sometimes, as shown in screenshots.
• Using HTML5 output

Attached is output from 'xpra info' command, debug output, and screenshots.

Reproducible using this container

This is for the latest RPM BETA build of XPRA for Fedora:latest (25)

Please always specify the exact version, see wiki/ReportingBugs which explains how to do this and why this is important.

Can you please include the full and exact commands that you used to start this particular desktop environment? (xpra start-desktop --start=...)

Resizing windows sometimes leaves artifacts, as shown in screenshots.

Does the problem go away if you run the server with:

XPRA_SCROLL_ENCODING=0 xpra start ...

Is your browser window using any form for zooming?

I will try to reproduce, but probably not before next week.

Hi Antoine,

Exact commands used to start:

dbus-daemon --system --fork
xpra start-desktop --start=lxsession --daemon=off \
  --bind-tcp=0.0.0.0:8080 --no-mdns --html=on \
  --no-notifications --no-pulseaudio \
  --debug=all \
  --dpi=96

Version is xpra v2.1-r16126

No browser zooming.

XPRA_SCROLL_ENCODING=0 does not appear to help

desktop screenshot (shrink screenshot size so we can inline it)

removed gzip compression so we can look at it more easily

Inlined screenshots:

• desktop:

• partial window:

• odd font spacing:

• popup menu font too big for menu entry size:

Tested again with the latest beta builds, and I'm not seeing any visual artifacts. In fact, the feature works surprisingly well.

Please try:

• connecting with a regular python client, can you reproduce any font problems with that one?
• use a different browser - does it make any difference?

Not heard back. Closing.
