Unfortunately, it looks like gamescope just isn’t going to work for my system.

It didn’t seem to have an effect, unfortunately.

I’ll take a look into that. This laptop is using one of those hybrid Nvidia GPUs, so it took me a bit to work out the performance issues at first.

I’ll give that a shot tonight and let you know

It does not seem to work for me. After inputting

wmctrl -a helldivers -b toggle,fullscreen

I just get a quick black flicker and it goes back to minimized. I also tried changing the win argument to :SELECT: from the documentation you linked, but it still doesn’t pull up the window and keep it there.

The command does work for other windows, for clarification.

An extra detail: I’m using 2 monitors. When playing with borderless window and moving the mouse rapidly, I’ve had my mouse escape the focused window a few times and start clicking stuff on my desktop.

From what I’ve looked up, it does. However, at some point the ability to change border settings in Themes was removed.

I just gave that a shot. When I come back and re-fullscreen, the game minimizes and goes back to the problem state.
