Bug#983390: mesa-vulkan-drivers: bad interactions between VkLayer_MESA_device_select and other layers
Recently, Mesa 20.3.5-1 was unblocked for Bullseye, and has resolved
most issues I had encountered since upgrading from Buster on a test setup.
The notable exception is MangoHud on 32 bit Windows applications in
Wine, which still dies rather silently on launch. Although not in all
cases, since for example very old games that won't touch Vulkan at all
and run completely through OpenGL work fine.
This still needs the workaround of either setting VK_ICD_FILENAMES
appropriately, or making /usr/share/vulkan/icd.d/lvp_icd.i686.json
unavailable.
I tested this with both MangoHud 0.6.1 (i386) from current Bullseye, and
the upstream binary 0.6.5 release, same behaviour respectively.
But I'm unqualified to tell if this is still a Mesa issue, or needs to
be resolved in MangoHud.
Still a massive improvement from 20.3.4-1, so big thanks anyway :-)
