Fullscreen applications behave weirdly with applications switcher and custom shortcuts

Note: I'm unsure if this should be one or two questions, so I'm combining them due to the related nature of the issues I'm experiencing.

I'm someone who likes to play a lot of videogames, and I'm also someone who likes to automate actions using custom shortcuts and macros on my mouse and keypad. I prefer to play games in fullscreen for a variety of reasons, but I've been experiencing a litany of (seemingly) related issues with fullscreen apps:

  • When I tab out of a fullscreen app, I cannot interact using the mouse with any other application. The keyboard works fine, however.
  • When I use the application switcher to quickly unfocus a fullscreen app (Alt+Tab once), it switches to the last app I used as I would expect. However, when I try to switch back with a single tap, it instead switches to the app I used two switches ago rather than going back into fullscreen. I have to repeatedly press tab to cycle back to the fullscreen app.
  • When I use any custom shortcut, including things like volume up/down, it forcibly unfocuses any fullscreen app I'm currently using, unless the application intercepts the shortcut for its own purposes.

Obviously this makes using fullscreen very difficult, and I doubt it's the intended behaviour for most cases (although I can understand if it is for shortcuts that spawn a process). What causes this issue? And if it is intended, how can I change it?

Edit: Thought I should mention that this happens with any fullscreen application, not just games, and if the app sets a custom cursor it remains even when tabbed out of the app.

Not normal behavior - you should be able to seamlessly switch between full screen apps. You may need to add information about your hardware.

Could this be caused by hardware? If so then this is probably just another nvidia issue, since my GPU is a nvidia quatro k6000.

Perhaps yes. You are running X11, though, so that should be proven. Perhaps try a (temporary) new, fresh account to see if the issue also reproduces there. Is this an upgrade? If yes, you may have more success with a fresh install.

I've reinstalled a few times after upgrades trying to fix this, but the issue has remained since 18.04 no matter how many times I upgrade or reinstall.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
