https://bugs.freedesktop.org/show_bug.cgi?id=93147 --- Comment #3 from Dave Witbrodt --- (In reply to Michel Dänzer from comment #2) > Does running the affected apps with the environment variable > LIBGL_DRI3_DISABLE=1 avoid the problem? Yes, symptoms are completely eliminated in prboom-plus when using that variable. (I am currently using a kernel built from a local branch with fa4270d8 and 4dfd6486 reverted, but I have left my previous kernel installed. I tested by rebooting to the previous kernel, and running prboom-plus with and w/o the variable set.) -- You are receiving this mail because: You are the assignee for the bug.
