[xmonad] The transparent borders on RGBA windows are back

[Adam Sjøgren]

After updating packages¹ on my Debian unstable laptop yesterday, the
transparent borders on RGBA windows are back².

Specifically if I open a Sakura³ window, the borders are see-through.

I am running xmonad 0.13-6+b2, libghc-xmonad-dev 0.13-6+b2,
libghc-xmonad-contrib 0.13-1+b2, libghc-x11-dev 1.8-3,
libghc-x11-xft-dev 0.3.1-11+b5.

Looking in ~/.xsession-errors when I open a Sakura window, I see no
errors from xmonad.

(Closing the window I see "user error (Error in function
getWindowAttributes)", but I guess that's not important.)

Looking at the changelog from the xserver-xorg-core package, I see this
interesting entry:

[ Timo Aaltonen ]
* New upstream release.
* 07-glx-do-not-pick-srgb-config-for-32bit-rgba-visual.diff: Add a
patch from upstream to fix potential issues with mesa git.

Sounds like that could be the reason.

Does anyone else see this? Any suggestions on how to debug/fix it?

I'm as clueless as last time⁴.


Best regards,

Adam

Sounds like that could be the reason.

Downgrading the xserver-xorg-core package to the previous one fixes the
problem, so it would seem that it is.

I have reported this to the Debian developer.

I don't know, however, if this is something that needs to be fixed in
XMonad or [Debian's] X.org.
