--- Comment #9 from Xylemon xylemon@posteo.net --- I tried to reproduce this with the CD Release (1.1.1.0) on Wine 7.1 and I could not get the menu to bug out like before.
In my test I left the game opened for about an hour in LAN, played some of the campaign, and even with played mods since you can load them with the main menu in this version. Tested on KDE Plasma 5 and WindowMaker
For some context, the CD Version has a Windows MFC window that then loads the game engine, and each button on the menu loads a new MFC window displayed ontop of the previous one.
The bug itself was that after playing the game for a while (20+ mins), clicking any button would play the animations on the buttons but never load the next menu. This is different from the Steam version, where the entire menu is always rendered in-game.
Wanted to clarify some of this since my original comments on this issue were ignorant/not too helpful I felt.
In short, so far to me it seems fixed in current wine.
