I have two monitors. The monitor in which I run Osu! has native resolution of 1920x1080, but I run Osu! on 1366x768 Fullscreen. On launch it works just fine, however if I, for any reason, switch from Osu! to some other program (Chrome for downloading new maps, for instance), whenever I switch back to Osu! the Windows taskbar is over it (despite Osu! being launched in fullscreen). Of course, when I click the taskbar, Osu! minimizes. The only to make it go away is to set Osu! to Windowed mode and back to fullscreen, which annoys me a lot. I have already tried running it in 1920x1080, but that doesn't help.
It didn't use to happen, but I had to reinstall due to a system format and it started happening right from install. Also already tried reinstalling again, turning Compatibility mode on and off, practically tried every possible option ingame. It's probably something wrong with Windows, but I don't know what to do anymore.
