            Bug ID: 104597
           Summary: Compton weird colors
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

Desktop with compton --backend glx

RX 480, mesa master.

Running compton --backend glx produces the effect in the attached image. The
colors are corrupted, but some applications look correct.

There is one situation where I have seen a similar effect not involving compton
and that is kwin's window preview of SteamVR's vrmonitor:
https://www.youtube.com/watch?v=IHHQS_Q5uqE. All other window previews work
correctly, it's only the vrmonitor that's broken.
But that's enough to say it's not a compton specific problem.

It could be similar bugs in compton and kwin. :)

If this started recently, maybe you can try bisecting Mesa.

I wonder if this might be related to bug 104599.

bug 104540 is probably the very same issue, since OBS uses Xcomposite to
capture a window.

Can you try what happens if you add the following snippet
inside the <device> section of your /etc/drirc and restart compton?

<application name="compton" executable="compton">
    <option name="allow_rgb10_configs" value="false"/>
</application>

The output of xdpyinfo and glxinfo could also be useful.

To disable the new rgb10 support globally, one can add this snippet instead:

<option name="allow_rgb10_configs" value="false"/>

xdpyinfo

No need to add to drirc, you can also set drirc options with an environment
variable.

This indeed works fine, no color issue:
allow_rgb10_configs=false compton --backend glx

compton didn't cause problems for me under default 24 bit color-depth on
X-Server 1.19.3.

But Christoph's setup is running the new server 1.19.6, and the glxinfo shows
various new 32 bit visuals, not only rgba 8 8 8 8 but also rgba 10 10 10 2.

1.19.6 contains the patch "glx: Duplicate relevant fbconfigs for compositing
visuals" backported from master, adding lots new 32 bpp compositing visuals, so
that might trigger the problems?

The broken window preview is actually a bug in plasma.

The thumbnail code doesn't look at the sizes of the color channels; it only
checks that the GLX_BUFFER_SIZE matches the depth of the window.

Possible fix, tested against server 1.19 branch.

This patch fixes the problem with compton, as tested against server 1.19
branch. Also applies cleanly against master, but i haven't tested it on master
yet.

So far tested with KDE-5, compiz, and compton, on ati-ddx under Radeon gfx,
both screen depth 24 and 30.

tested here 1.19 as well, sadly does not fix the issue with OBS xcomposite
window capture mentioned in https://bugs.freedesktop.org/show_bug.cgi?id=104540

That probably means it's an OBS bug, not handling 10bpc configs correctly.
Please report it to the OBS developers.

Looks like it's the same as
https://obsproject.com/forum/threads/xcomposite-colours-all-wrong.81265/ and
https://obsproject.com/forum/threads/xcomposite-window-capture-not-working.81389/.

It's been pointed out it's not Obs as TyMiles2012 moved back from the Oibaf PPA
on Ubuntu 17.10.1 back to standard drivers and it no longer affects him.

That doesn't mean it's a Mesa bug, just that the OBS issue was triggered by a
change in Mesa's behaviour (it now exposes 10-bit-per-component colour
configs).
