Reposting this here because I think this is a better place for my question. I just reset my pc completely and now face this issue after alt tabbing out of games like csgo and league. My games are set to fullscreen windowed and I have tried using borderless gaming to fix it to no avail. I have also noticed that it effects the league client and discord aswell as I cannot click out of them when they are minimized in window mode, so I think my computer thinks that everthing is in fulllscreen mode when nothing is... Any help would be great, thanks.
