Basically if MapleRoyals is in Windowed Mode and I press Alt + Enter to return it to Full Screen, it will sometimes cause my screen to go completely black. I can still hear MapleRoyals music but the game is unplayable. I can't fix this. Alt tab doesn't work. Alt enter doesn't work. Ctrl Alt Del will take me to a screen with the following options: lock the computer, switch user, log off, change password, start task manager. There's also the option to shut down, restart or sleep. I click task manager and I briefly glimpse some programs before the screen quickly returns to black. This is incredibly frustrating while bossing. During Zakum I have to GFX or the body will "blink" (disappear and reappear). It caused my client to crash once. For Horntail the Wyverns would "blink". GFXing will cause my client to to enter window mode and I want it to stay full screen for boss battles. I tried googling this but this seems like unique issue. Any tips or should I just keep MapleRoyals as it is during boss battles to eliminate the risk?
