New glitch - heavy UI flicker

[Jaguarete]

Today I logged into DDO only to find new graphics glitch:
UI flickers and flashes badly. So badly that I cannot look at it more then few seconds.

It happens all the time if:
you are in the building, like Cannith Crafting Hall or Bank
AND
you have special NPC in view - like banker, auctioneer, or even postal box.

It happens sometimes on the open - I found place and view direction, that causes flicker near guild ship door in Marketplace.

Only thing I changed in system is updated VCC x64 to make new Skyrim run.
And it also have UI flicker issues, luckily I got it free in Steam and not even planning to migrate to it from classic Skyrim.

Windows 7 x64, NVidia GTX 550 Ti. drivers 375.70WHQL

Any suggestions?

Switching from "Full screen" to "Full screen - windowed" solves the problem, but root cause is still unknown.

I had something similar today. Full screen had constant purple flicker, windowed was fine. I changed the in game option to direct x 11 (somehow had defaulted back to dx9) and flicker went away.

Good luck.
