#323 closed defect (fixed)

Screen redraw missing a single-pixel column

Reported by: Mark Hills Owned by: Antoine Martin
Priority: minor Milestone: 0.9
Component: core Version: 0.8.x
Keywords: Cc:

Description (last modified by Antoine Martin)

In several windows I see single rows or columns which are not redrawn.

This leaves a one-pixel row at the bottom or right, shown in the attached screenshots. The problem is easily reproducable. xosview is the default window size. The xterm has been resized by -1 text row.

The pixels are not drawn (as opposed to being drawn black, or white) so we see whatever was previously drawn.

$ rpm -q xpra
$ cat /etc/system-release
Scientific Linux release 6.3 (Carbon)

This should be fixed in r3133: in the cases where we have to trim the window size to match the video encoder's limitations (even sizes, etc), we now send the edges using a lossless encoder (png or rgb24+zlib).

I've also uploaded new CentOS RPM builds here (0.9.0-23) in the beta area

Please close the ticket if this also works for you - thanks for bringing this up, I was meant to deal with this a long time ago!

Tested the given RPM, and reproduced the xosview and xterm cases, all looks good. Thanks!
