On my linux machine I use a window manager that swaps between tabs using win + tab number. PICO-8 treats win same as ctrl and if I have PICO on tabs 6 through 9 it makes screenshots, gifs and label images when I switch to (or sometimes from) it. In config there's an option to disable this functionality with function keys F6 through F9, but I would like it to work ONLY on function keys or just not recognise win as ctrl, though I might be the only one. Til then I'll keep PICO-8 on tab 5.

I have a very similar setup with win+n bound to change desktop but I've not come across this problem with Pico-8. Which WM are you using?

@stilvoid qtile with as little change to default config as I could.

Weird. Checked what xev says in case your keyboard is somehow mapped strangely?

Nah, it recognizes separate Control_L and Super_L keys with different keycodes and stuff. The WM also recognizes these as different keys as it doesn't trigger the tab change with Ctrl.

Also PICO-8 treats the Super key as Ctrl on my Windows as well, though it's not an issue there since there aren't any important shortcuts including Super + numbers.

Actually, I just tried this again now and I do see the behaviour you're talking about! I guess I just hadn't noticed before even though I do often have pico-8 on desktop 7 or 8!
