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.
