Alien: Isolation rendering on TURKS with Mesa git
Hi!
With Mesa 18.1~git180219165200.f78fe98 in Alien: Isolation there is renderi=
ng
artifacts - please look into attached screenshot. Issue is reproducible on
Radeon HD 6620G and 6650M.=20
Graphical settings is all set to minimal, all visual effects is disabled.
Kubuntu 17.10 x86_64, Linux 4.15.5
By the way this issue looks like bug 100387, but I not sure if caus= e is the same.
On BARTS this looks fine with 4562a7b0e82bf664b30 (2018-02-23)= . Do you have any output from logs? On my Cedar based card I get "CS shader rejected&quo= t; - and then the GPU to lock up (In any case, on that card even starting up the game is already only a slide show).
I might have been wrong, it is certain that eb96ba722ee7 worke= d, but checking out above commit after following Darius Spitznagel hint [1] Disable it in the prefereces file in ~/.local/share/feral-interactive/AlienIsolation like below... <value name=3D"EnableShaderWarmer" type=3D"integer"&= gt;0</value> I wasn't even able to start the game, because I got an LLVM error. Will bis= ect now ... [1] https://bugs.freedesktop.org/show_b= ug.cgi?id=3D104654#c8
Well, after a clean reboot 4562a7b0e82bf664 works fine on BAR= T. I guess the crash with the CEDAR card somehow triggered an instability that was respons= ible for the problems starting AI later (I use both cards in a dual head with separate X-screens setup).

I retested game on Mesa build 4562a7b0e82bf664, this time with "MESA_GL_VERSION_OVERRIDE=3D4.3 MESA_GLSL_VERSION_OVERRIDE=3D430 %comm= and%" launch option in Steam settings - issue is no longer reproducible.
