I'm experiencing a strange and very annoying problem with dissolves in my timeline. Whenever a dissolve begins, a black bar appears along the right edge of the frame that proceeds to fade out over the course of the dissolve. I'm working in a 2K project (1998x1080 DCI Flat) with DNxHR 444 media.
Here are screenshots of before, during, and after that I posted on Facebook because I can't figure out how to post them here:

Curiously, the problem did not exist during the offline phase, when every clip was at 5K size in a 2K project and had a FrameFlex spatial adapter on it. Now in the online, with media rendered out from the colorist at native 1998x1080 size, the problem is introduced. But it also happens on two 4K (3996x2160) clips in the timeline.
Has anyone else experienced this?
