I recently installed Linux Mint Cinnamon on a laptop, and I’m having a two-sided issue. Web searches have yielded no solution. I’m also very new to Linux.

Problem 1: When alt-tabbing out of a fullscreen application (at this moment, Helldivers 2), the application will minimize, but I cannot restore it. It will appear for roughly half a second, and then re-minimize. I can hear the game still running in the background.

I have tried alt-tab, super+number, and right-click>restore. None seem to work.
I have tried disabling thumbnails for windows, no fix.
Disabling effects, no fix.

Problem 2: As a workaround for problem 1, I tried borderless fullscreen. It works, but there is a white, 1 px border around the screen. I have tried changing themes, no fix. Same thing with disabling effects. I do like the Mint-Y theme, but there’s no longer an option to change window borders, from what I’ve researched. Again, trying a different theme didn’t seem to get rid of the white border.

Please help.

    From the description it feels like you’re not exiting full screen mode within the game before switching to other applications. Try the same key combination you use to enter full screen mode again, before switching.

    I have also experienced your first problem. It’s probably that the game bugs out in some way. apparently gamescope helps to fix it, bit I wasn’t able to get it to work on an nvidia based system.

      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.
