Issue:
When I alt-tab into the game, or otherwise click back into the game (running border-less windowed) my character will jump once on the spot. Also, when I fly on a mount then it will continuously fly up as if I'm holding jump, making it impossible to dismount or land without flying into Idyllshire, which will ground me.

The issue has been happening constantly for several weeks now, and makes it impossible to do any open world content that requires flying.

I checked my keybinds to make sure I didn't accidentally change something, but it remains the same as before. I even tried playing other games with the same jumping/flying control to see if it might be my hardware but I've been unable to replicate the bug or anything similar in any other game.
