TemporalAA Artifacts after switching from 4.7 to 4.10

The red balls are rolling from top to bottom, leaving red artifacts on the glowing borders of the floor. This is only since I moved from 4.7 to 4.10 today. Has anything changed with the AA implementation? Any settings that I could play with to eliminate these artifacts? FXAA doesn’t work, everything’s flickering. With supersampling it looks better, but drains the performance. Also tried the 3 TemporalAA console variables, no differences. If I can’t get rid of this, I guess I’ll have to move back to 4.7 :frowning: Any ideas?
