**NOT FIXED IN 15.4**Premiere Pro IS UNUSABLE - Trim Tool Flickers/Flashes + Choppy playback
I was let known that this bug would be fixed in version 15.4 but it wasn't.
I've been having a huge issue ever since updating to Premiere 2021
3 Months Ago..
On my timeline when I extend a video clip by dragging the ends with the selection tool, the preview screen flashes on every frame. It looks like it is flashing back and forth between where the playhead is and the frames I am extending.
Here is a screen recording of that happening in the current version 15.4: https://youtu.be/ImB9KaMOE4k
Every time I make any change or adjustment to any clip, text or basically anything on the timeline, the preview screen changes between aspect ratios, and low-res previews and then pops back to normal.
This happens Every time I even touch anything on the timeline.
This isn't an isolated glitch, either. It happens in every project I've started and opened.
I reset Premiere and trashed the preferences already. I have run out of options.
Has anyone else experienced this problem? Any help will be greatly appreciated as I can't even edit without near getting a seizure from the preview monitor flashing.

Hi Joe - Sorry to hear about your experience. We discovered and fixed the issue quite late in the release cycle and decided to hold off shipping it in 15.4. The good news is that fix is already out in Beta. Please try it out and give us any feedback you may have. We are also working on fast-tracking this and shipping as part of our next release. Hope that helps!
