Package:libgl1-mesa-dri Version: 20.1.7-1 Severity: important Dear Maintainer,
Occasionally the native linux 64-bit client of the mmorpg Champions of Regnum becomes unuseable with a messed-up display (no/transparent walls, invisible characters, grey backgrounds...) after a libgl1-mesa-dri upgrade. Currently, the last working release is 20.0.7-1 and I have to revert and downgrade to it as soon as I try a more recent release. Downgrading only the following 5 packages solves the problem entirely. aptitude: [DOWNGRADE] libegl-mesa0:amd64 20.1.7-1 -> 20.0.7-1 [DOWNGRADE] libgbm1:amd64 20.1.7-1 -> 20.0.7-1 [DOWNGRADE] libgl1-mesa-dri:amd64 20.1.7-1 -> 20.0.7-1 [DOWNGRADE] libglapi-mesa:amd64 20.1.7-1 -> 20.0.7-1 [DOWNGRADE] libglx-mesa0:amd64 20.1.7-1 -> 20.0.7-1 Best regards, VB
