I figured out why a rebuild helped; it's a shader cache problem, and Mesa's shader cache is keyed (among others) on the build ID. Unfortunately, even after clearing the shader cache, I can provoke these issues with a bit of work. So something is corrupting the shader cache. > So, please binNMU libgl1-mesa-dri for at least amd64, since this is > likely to break a fair amount of applications. You can disregard this part, then. /* Steinar */ -- Homepage: https://www.sesse.net/
