Bug ID: 103874
Summary: The Witcher 3: flickering regression with radeonsi
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: shtetldik@gmail.com
QA Contact: dri-devel@lists.freedesktop.org
With latest Mesa master, The Witcher 3 in Wine started performing worse and it
also introduced noticeable flickering (once in a few seconds).
I was able to narrow down this flickering to these commits by Marek:
adab7f16ffd3ea4c52e8d07f40ca6ae4868c3706 2017-11-06 radeonsi: don't map big
VRAM buffers for the first upload directly
4b0dc098b2561c07c59f7dab2813640a25789bf1 2017-11-06 gallium/u_threaded: don't
map big VRAM buffers for the first upload directly
a5d3999c31e2460f690b561b41170bb7bc24fc65 2017-11-06 gallium/u_threaded: clean
up tc_improve_map_buffer_flags and prevent reentry
One commit before them this flickering doesn't occur:
OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.18.0
/ 4.13.0-1-amd64, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.4.0-devel
(git-60a9705e00)
And with them, it does:
OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.18.0
/ 4.13.0-1-amd64, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.4.0-devel
(git-adab7f16ff)
I'm running The Witcher3 with mesa_glthread and csmt enabled (both). You can
use latest Wine staging to test it.
