When I first played Classic the other day I had no issues, only yesterday have I started to get a very quick bluish and reddish flash whenever I tab in or out of Classic or even change the volume the windows pop up causes it. I have my game in Windowed Fullscreen and I had this issue before on retail but to fix it I changed directx 12 to directx 11 because there is no option for this in Classic I’m lost on what to do.
Hey Siprus,
Let’s see if a clean installation of your graphics drivers fixes this for you. First off, please use a Display Driver Uninstaller to remove your current drivers, and install the latest drivers for your graphics card afterwards. See if that improves things.
Have a few seconds to spare? Let me know how I’m doing!
Google how to Disable Fullscreen Optimzations for a program. In your case..\World of Warcraft\_classic_\WoW.exe
And yes, also check that your display drivers are current.
First of all thank you for getting back to me! I done the process and fully uninstalled my drivers then reinstalled updated drivers and I still have the issue with tabbing in or out.
