Steps of reproduction

// If you can reliably reproduce this bug, please describe the quickest way to do so // This information will greatly help us diagnosing and fixing the issue.

1. Start awesome 4.3
2. Start compton
3. Start something that triggers desktop notifications (but this doesn't happen just with notifications, and doesn't happen every time - sometimes menus get wonky too but it's easiest to trigger with notifications). Tested with quasselclient and awesome-client "error()".
4. Stop compton, repeat 3.

Expected behavior

Notifications would appear normally.

Current Behavior

Notifications appear corrupted. They appear with 8x8(? didn't actually measure) lines, offset in a pattern. Additionally, these lines also have areas of random stuff on them (uninitialized memory maybe?).

Stack trace

// If compton crashes, please make sure your compton is built with debug info, and provide a stack trace of compton when it crashed. // Note, when compton crashes in a debugger, your screen might look frozen. But gdb will still handle your input if it is focused. // Usually you can use 'bt' and press enter to get the stack trace, then 'q', enter, 'y', enter to quit gdb.

// Or, you can enable core dump, and upload the core file and the compton executable here.

Other details

// If your problem is visual, you are encouraged to record a short video when the problem occurs and link to it here.

Update: I've also had this issue with the quit dialog from guake, still using awesome WM. Definitely leaning towards compton issue.

[yshui]

Do you have a screenshot?

[SoniEx2]

if I can figure out how to get github to accept it

[SoniEx2]

eh, I give up. anyway: <magnet:?xt=urn:btih:551650b47b662f2b49608949c040c91c0c2b7408&dn=1555245493.png&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce>

[SoniEx2]

imgur won't let me upload either, and additionally imgur is known for adding compression artifacts.

in any case, I am seeding, and I was able to leech onto my phone. if you can't leech, check your ISP, the tracker status, or your DHT settings. it's a fresh torrent so expect it to take a few minutes.

[Clyybber]

Huh, weird. It works now, I have uploaded it here for convenience: https://i.imgur.com/8YZHz8r.png Btw, imgur's compression only kicks in for very large pngs. For smaller ones such as this one it doesn't change the file.

[yshui]

Could be a driver bug. I will ask around.

[SoniEx2]

Could be a Cairo issue... I believe I've only had the issue with GTK apps and the WM, which as far as I can tell uses Cairo...

Will do more testing with Qt later today.

[yshui]

@SoniEx2 Does this problem happen if you uninstall xf86-video-ati and use Xorg's builtin modesetting driver instead?

[SoniEx2]

Removing xf86-video-ati has made the issue disappear, or so it seems...

[yshui]

@SoniEx2 So, if you are certain you were indeed using xf86-video-ati version 19.0.1 before (there was a similar problem in 19.0.0 that was fixed in 19.0.1), you can open a bug report here:

https://bugs.freedesktop.org/enter_bug.cgi?product=xorg&component=Driver/Radeon

You should try to include as much information you could, also remember to mention removing xf86-video-ati fixes this problem.

I am going to close this bug since it's likely not a compton bug.
