Bug ID: 102796 Summary: steam not rendering correctly on VEGA 56 Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: tomenglund26@gmail.com

im using amd-staging-4.12 branch from https://cgit.freedesktop.org/~agd5f/linux/

gist of dmesg https://gist.github.com/gulafaran/af0edfff6dabafe12f451a2caaa5bd58

tried on mesa 17.2 release and 17.3.0_devel.95819.9aba643e3c-1

and tried both llvm 5.0.0 and 6.0.0svn_r313351-1

03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Vega [Radeon RX Vega] (rev c3)

steam doesnt render quite correctly as can be seen here https://i.imgur.com/gRxuOz8.png , no particular error is printed to stdout or stderr nor dmesg. ive tried various games and benchmarks which all works just fine. its only steams GUI thats misbehaving so far.

no change running it with STEAM_RUNTIME=0 or 1, same goes with STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0 or 1 .

and this happend when i switched from nvidia card to the vega 56. so the steam install should be fine as it has been working on nvidia blob and nouveau, even tried removing and recreating the ~/ steam files.
