Some tree models flicker
You must change the window from fullscreen to windowed (or vice versa) for the content manager to show or update text
Trees sometimes flicker depending on the route and tree model, and the content manager text issue is quite annoying. However, it runs well framerate wise on Linux for some reason, and better than Windows for me. That was good to see though.
Major features are difficult to access
Content manager does not render text
Performance is on par with windows in Proton Experimental
Content Manager and Content Store do miss font. Maximizing the windw or pushing it outside and back to screen does render correct data. Might be a local issue. Missing confirmation. Rest of game is unaffected of this.
pure game play should work. special cases like html assets, content creation not tested yet
mouse was a bit too sensitive
"Manage Content" now works compared to previous proton versions. A bit slow maybe but usable

launcher works but in game menu doesn't display
Screen of "Manage content" seems borked. PS: game seems playable in wine staging 5.10
Proton 5.4 GE-3

Launcher runs fine, but after hitting Start Trainz black screen with audio playing no matter which switches I have tried or even versions of Proton
