Proton: 9 to 11

A really weird issue where a Realtek bluetooth dongle causes certain games to crash. No devices need to be connected, it just has to be present. Removing the dongle fixes all issues. The crash usually happens 5 - 60 minutes after starting a game

Games where I noticed the issue:

  • Kingdom Come: Deliverance 2 (controller connected via bluetooth)
  • Ostranauts
  • Cosmoteer: Starship Architect & Commander

I know that Realtek and linux do not play nice and am planning on buying a replacement anyway, but i though i better report this anyway
