Sorry to revive this old old old thread.
The driver thing never solved the windows button graphic corruption mentioned above.
I eventually got around it by skipping Standby mode altogether and just use hibernation. This worked for a long while, and now... the problem also happens when using (coming back from) hibernation!!
One clue that could help me to solve the problem -- maybe -- is that when Windows buttons are corrupted, it's impossible for different backup apps to rely on the Volume Shadow (Copy) Service . Basically, when buttons are distorted, I know for sure that VSS won't work
Maybe some window expert here would know how these 2 problems could be linked ? That might
help me solve the problem (instead of rebooting each time I need to do a full backup or bring back my buttons...).
PS : I did many searches with different terms and never found anything interesting in relation to the problem. Terms I tried were: Window(s) button(s) corruption garbled
in different combination, of course. If you guys have any suggestion for a web search, I'm all ear as English is not my main language.
