Symptoms

1. The game runs really well under the Proton Experimental compatibility layer; however, crashing will occur after loading into a battle. After about a few seconds, the game will freeze and stop responding.

This might be due to the Steam overlay, adding LD_PRELOAD="" %command% in the launch options stops the crashing.

2. Video files do not load.

The only real fix for it is to put PROTON_USE_WINED3D=1 %command% in the launch options, and switch to Proton GE. The WineD3D renderer runs really slow at high resolutions for me, so I keep the resolution at "800 X 600" for both "Strategic Map Resolution" and "Battlemap Resolution."

3. Downloading shader pre-cache causes game to not start.

Reproduction

1. Launch the game with the Proton Experimental version.
2. Start a tutorial mission and load into the game.
3. After a few seconds, backout of the tutorial mission.
4. Repeat steps 2 & 3 for about 3 to 4 times.
5. Game will freeze.
