should fix it.
If it doesn't then:
Ensure that you have the following registry value set to :
HKCU\Software\Microsoft\Windows\DWM\Composition set to 1 (32-bit DWORD)
HKCU\Software\Microsoft\Windows\DWM\CompositionPolicy set to 2 (32-bit
DWORD)
2/ Restart DWM by opening a command prompt with administrative privileges :
- Type 'net stop uxsms'
- Then 'net start uxsms'
If there is an advanced display properties tab>troubleshoot tab or similar
for that card, when you go to Personalization>Display Settings (link towards
bottom) then push the acceleration level all the way to the right, and
enable "Write combing." All of this is dependent on any settings like t
his available at this location.
Good luck,
