--- Comment #2 from Sergio <sergio.calleg...@gmail.com> --- The matter is not completely clear to me, because the discussion on the mesa tracker (also including https://bugs.freedesktop.org/show_bug.cgi?id=103699 which is probably related) seems to suggest that "Problem is that GLX may pick sRGB capable config for 32bit visual that is used for translucent windows and compositor (kwin) does not seem to do blending properly in this case as it seems not aware of sRGB at all". If this is the case, the upgrade of mesa may have only triggered a "re-ordering" of the visuals favoring the choice of the one that Kwin is not aware of. As a matter of fact, mesa appears to propose to disable sRGB globally 32bit visual for now /as a workaround/. -- You are receiving this mail because: You are watching all bug changes.
