I got a copy of this game in the first week of September 2025, my computer runs Windows 11. When I launched it from GOG client and went to the game library, the screen kept flashing repeatedly. It still received button controls in each game, but the flashing made it unplayable. In GOG discussion thread, user 'larrie' suggested a fix like this, which works for me: - Open the game folder. If you used the default installation, it should be in `C:\Program Files (x86)\GOG Galaxy\Games\Atari 50 The Anniversary Celebration`. - In the folder, you will find a file named `atari50.exe`. Right click it, choose 'Properties'. - Choose 'Compatibility' tab, select 'Disable Fullscreen Optimizations'. Click 'Apply' then 'Ok'. => The game should run fine now without the flashing screen.
