When playing eve online on Linux (via Proton), the moment any other window gets focus, or the mouse slights off the game screen onto the second monitor on the side, game minimizes.
I have a feeling it's just wine things. Can anybody understand what happens and maybe explain it a little?
I remember that 13 years ago I did everything on Linux and only switched to Windows to play eve online. Now the game works beautifully (graphics and all) on Linux with just one slight modification in the "run command" in Steam.
This is nothing, as anybody who tried to play games on Linux using wine can attest. It used to be a hell of modifications, dependency hunting and obscure hacks to get any windows game to work.
Proton and Vulcan are Awesome.
Try running it in gamescope. Or the "always capture mouse in fullscreen windows" setting in winecfg.
Check your mouse focus settings in your desktop environment (gnome/KDE/whatever).
There may be an option called mouse stealing prevention or something, but if you have a look you should hopefully see it. On xfce it's in its own tab in the mouse menu
Vulcan is the home planet of Spock, the 3D API is Vulkan ;) (sorry for nitpicking)
There is a weird bug in Helldivers 2 when you use the maximized window without borders and you have a multi monitor setup. Sometimes, the character stops of rotating with the mouse look... like if the mouse cursor found a limit. Another, it's with the full screen mode. When I switch windows with AltTab, sometimes the game restores with the wrong display proportions.
As far I know, this bugs happens on Windows too.
Not sure why that happens, but you may want to try "borderless window" instead of fullscreen in the game options. If that does not work, you could try running the game in gamescope, or enabling the wine virtual desktop with winecfg (point it at your game-specific wine prefix, you can also run it from protontricks). These are just a few ideas, but it does sound like a mechanism that is part if the game, not wine. Just like some games crash when you alt-tab in windows; gamescope tends to fix that.
