Hello @mcoulont, there's not enough information here to even start pondering your issue since you've omitted any actionable details.
If you're testing a Linux native game (or a Windows native game on Windows), that should be mentioned to the game's developers. Alternatively, if you're testing a Windows based game being run with Proton on Linux, then that should be mentioned on the game's compatibility report on the Proton issue tracker.
Closing as not a Steam client issue.
