Using a tiling window manager, if I have two windows side by side and then full screen one, then the other will be resized to full screen size when it is not visible. If I then switch to that window, I will see a black region in the window which covers the newly added space. If I then resize the window again while it is visible, the bug goes away.

Here is a screenshot:[[Image(fullscreen.png)]]

You can see that the bottom half of the window is black.

This is on:

$ xpra --version
xpra v0.17.5

Please provide:

• which window manager can be used to reproduce (exact version, distro, etc)
• which applications are affected? (all?)
• "2 windows side by side", what windows are those? Does it matter?
• please attach the "-d geometry" debug output (both client and server)
• can you reproduce with a supported version? (0.17 was EOL last year)

1. stumpwm on debian jessie: https://packages.debian.org/jessie/stumpwm
   version 2:0.9.8-7
2. All applications are effected.
3. Doesn't matter. To reproduce press ctrl-t s ctrl-t q with two xpra windows open. The one that isn't focused will be cut when you use ctrl-t space several times to switch to it.
4. I'll get back to you on this in a moment.
5. Is there something wrong with the debian packaging process? Sid still has 0.17 https://packages.debian.org/sid/xpra

Do you have those log samples?
I'll try to carve out time to test this during the 2.1 release cycle - doesn't look too hard.
As for sid shipping a broken version, this is a recurring theme which we have documented: Packaging DistributionPackages.

Sorry for not getting back to you sooner. I got sidetracked by my inability to tell xpra where to store the log file. Despite setting the --log-file flag, it seems to always store it in ~/.xpra/Xorg.:100.log . Thus my email question about why the if statement was written that way.

But that doesn't give me a client log file and this mess isn't really readable for you: (So I'm going to have to launch xpra normally and not in a container.)

Despite setting the --log-file flag, it seems to always store it in ~/.xpra/Xorg.:100.log
The "log-file" argument is for xpra's log file, "Xorg.:100.log" is Xorg's log file, not xpra's.
You can modify where that goes by editing the xvfb command line.
I had to edit comment:4 because the indentation was really messed up, never seen that before!

There's a client log file for what seems to be the same bug here: #1469#comment:2.

Aha, I think that this is clearly a dup of #1469.

Probably caused by buggy Intel drivers, see #1469#comment:14.
