I installed a Nvidia update from 14th february last night and since then I have had really bad screen flickering on wow. Especially the dome around haven flickers a lot…I thought I had found a solution yesterday as it set my default screen to 2 instead of 1 but it seems to be worse again today…
Anyone else have this issue or a solution?
Display flickering with specific Nvidia drivers has been a problem in the past, but we don’t have anything specific on the radar for the most recent version of said drivers.
I would recommend to manually fully uninstall said drivers (a tool like DDU might help), and then re-install them cleanly - with any luck this is just the result of relics of an older drivers interfering here. 
I can confirm that. I have seen preety much a lot of flickering for the past few weeks. Dome around Haven flicker for me too and also I have seen flickering objects in Qeen’s Conservatory, waterfal and mushrooms. This happends ocasionally.
I have latest drivers 511.79 and always using DDU.
Just did SoA and it got really bad when I went up any stairs >.< also flying flying through the streams connecting zones…
Tried the fix stated above and seems to have fixed some flickers but not all.
