--- Comment #3 from Matias N. Goldberg dark_sylinc@yahoo.com.ar --- I'm on:
OpenGL renderer string: AMD RAVEN (DRM 3.30.0, 5.1.15-050115-generic, LLVM 8.0.1) OpenGL core profile version string: 4.5 (Core Profile) Mesa 19.2.0-devel (git-8305766 2019-07-11 bionic-oibaf-ppa)
And I can also still repro this issue. Firefox isn't the only way to trigger it, Chromium can trigger it too.
Is it too old already? How recent the kernel and mesa must be?
