Screen getting faint in back round when a Prompt comes up is not an issue if this is what you mean to. Uninstalled graphics drivers many times, but have you ever tried an older version of this driver, say right before this new one ? Now never tried how it reacts in safe mode to eliminate the possibility of another driver or software and or running process.
Third party Themes i am not sure if will cause an issue as i never used one. Another thing mentioned way back in this post was to use a program called HWinfo to monitor temps for graphics card. Testing the Graphics Card will stress it to see how it reacts temperature wise and if there is an issue, first see how temps are then with HWinfo and try in Safe mode.
As can be hardware, but as mentioned can be some other process (software) or driver conflicts.
