Issues unresolved
Wayland incompatibility
- As of September 30, the game isn't compatible with Wayland.[4][5] To get it working with Wayland, you must bypass the launcher and disable MSAA as a workaround. To bypass the launcher, add "-nolauncher" as a Steam launch option. To disable MSAA, go to ~/.local/share/Paradox Interactive/Hearts of Iron IV/ and set the value for "multi_sampling" to 0 in the "settings.txt" file. Please note that if this workaround is implemented, you may also need to manually set the screen resolution in the "settings.txt" file as well.
