Bug#1104326: Apparently Fixed in mesa 25.0.5-1
A lot of users (myself included) started hitting game startup
failures with Proton 10/experimental and 9/hotfix recently (also
with Proton 8 on some systems), where dropping back to something
like Proton 7 got things working. The Proton devs attribute it to a
recent Mesa regression supposedly fixed by
https://gitlab.freedesktop.org/mesa/mesa/-/commit/ac96c18 in Mesa
25.0.6 (not yet in Debian). If you're experiencing a problem along
these lines not fixed by the recent 25.0.5 packages and have an AMD
GPU, then it might be that.
