in release highlights of 343.36 driver we see:
Fixed a bug that rendered very bright garbage data onto some textures in UnrealEngine 4 applications. This issue is known as the “disco bug” by the UnrealEngine 4 Linux community.
I have (and other people has) this issue on legacy products like GeForce 8800 GT or GTS 250 with latest driver 340.76, 340.65 playing UT4 pre-alpha.
(tried older ver. with no luck - memory corrupion… and core dumped)
340.76 display driver was released five months ago - so the question is: will we see bug-fixed driver for legacy cards?
