Bug Report: After Effects 15.1 Black vertical lines when scrubbing timeline / Windows 10 / UI Scaling other than 100%
On Windows 10, using AE v 15.1.0 and nVidia Driver v 391.35. Have UI scaling set to 125% (have tried custom as well) on a 3840x2160 monitor resolution. Any scaling other than 100% causes this issue. Black vertical lines appear on the timeline layers when scrubbing. When you stop they go away usually. There is also a slight shift of 1px probably, and a strange minor blurring of the timeline layers while scrubbing. If set to 100% UI scaling, all issues are gone.
This was not an issue with the previous version of AE.

There are black vertical lines while scrubbing and playing the timeline, this happens on 2 pcs i have- there is also some weirdness on the tabs - they have white outlines and gaps inbetween them _(eg between align and paragraph tabs)
one pc can be fixed by turning the scaling down on windows 10- but the other pc this has no effect
this has happened on previous versions but they were fixed, and now its returned
