Yes, always happens at the same place with Citra emulator, however what bot=
hers
me more about the bug is that sometimes it happens completely randomly on my
system without any really obvious triggers while just browsing and using my
desktop, so it's not Citra exclusive, but luckily I've found the Citra meth=
od
to provode the bug so we can do more detailed logging.
Further observations:
- Bug is the same-type as other crashes and is not Citra emulator exclusive,
happens on Rocket League on launch as well and sometimes randomly while usi=
ng
the desktop
- Same type of crash IS NOT reproducable on Windows on the same GPU
- Same type of bug IS NOT reproducable on my IntelHD laptop with same versi=
ons
of MESA/LLVM which probably means either faulty AMD kernel driver or faulty
Firmware binaries.
My versions are:
MESA: Mesa 19.3.0-devel (git-6775a52 2019-09-02 eoan-oibaf-ppa)
Kernel: Ubuntu mainline 5.3 daily build (I ALSO tried amd-drm-next-5.4, same
bug is reproducable)
Firmware binaries: 2019-08-26 from /~agd5f/radeon_ucode/navi10
