Rename/delete libGLESv2.dll in the game director and it plays well.

I have a simpler fix. Just move/rename/delete libGLESv2.dll in the game directory that contains "The Miskatonic.exe". I changed mine to libGLESv2.dll.bak Tested with a fresh Proton 5.0 prefix. It just works after that. Use the other fix if you prefer to leave the files in the state they were downloaded, either way works. Played about an hour into the game, no issues.
Same as before, just need to click the window once to bring into focus to allow a switch between windowed and fullscreen.

The game installs with a version of libGLESv2.dll in the base installation directory. You want to ignore it and use the builtin version that ships with Proton. To do this you must run winecfg for this prefix and then go to the library tab. Once there add a new override rule for libglesv2.dll . After adding the rule edit libglesv2.dll override to "builtin (Wine)". Then hit OK closing winecfg. Your done! Just start the game normally now.
Small issue. Pressing the "f" keyboard key switches from full screen to windowed, but after each change it is required to left click the window once to bring it to focus. After doing so everything works fine and also allows you to switch back to either fullscreen or windowed another time.
Black window and Cursor only.

Opens a black window where music eventually plays. None of the standard Proton tweaks have worked.
