I have 2 monitors in my setup both are 1920x1080 res.
When I make discord go full screen on one or the other about a pixel wide edge of it bleeds over to the other screen, so I have a thin grey line going down the side of it.
So seems discord is not scaling to the screen correctly. Anyway to fix this? I think it is causing issues with some games, most notabley Borderlands 3.
If I have Discord full screen on the my secondary display while playing the game, Borderlands 3 will go 'black' on and off until I alt-tab out and minimize Discord or reduce the windows size and also require me to switch the game from full screen to windowed and back again. (Otherwise it's quit out and relaunch the game)
This does not occur if I make sure Discord is not full screen on the other display when launching the game.
