Hello @p2ndemic, sorry but this feedback is not coherent. <Undescribed> <video reference> of something related to Monster Train 2 apparently does not and does occur with Proton Experimental. If you're seeing an issue unique to a third party build of Proton, it'd be better to mention your findings to the maintainers of the third party build.

@kisak-valve

I have updated the issue description. Please do not close the request without properly reviewing the problem - this approach is unethical.

Previously, I contacted the GE-Proton developer. He investigated the issue and confirmed that the problem originates upstream, therefore it needs to be addressed here.

Please review the request. Thank you

For clarity, are you referring to the placeholder video in your recording? Calling ethics into question is not the issue here, your contradictory minimal communication is the reason the compatibility report was closed.

Please add PROTON_LOG=1 %command% to the game's launch options, reproduce the issue, and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.)
