[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
