Bug#914267: mesa: [regression] with Mesa 18.2.5-2 the charackter model in Tomb Raider is no longer rendered.
Package: mesa
Version: 18.2.5-2
Followup-For: Bug #914267
That looks like missing shaders. I hit a similar thing with mpv (just
blue window, sound but no video) after upgrading 18.2.5-1 => 18.2.5-2,
luckly showing some output that later helped with searches.

Bug 914303 could be the same too, garbled or single color output could
mean shaders not working because they failed to compile. Looking up
the error text, I found the culprit could be gcc, creating faulty
mesa binaries. https://bugs.freedesktop.org/show_bug.cgi?id=108646
