One clip flickers during preview

Please don't relocate this question. The other similar questions I've found are all dealing with post-export, my problem occurs during editing in preview and remains an issue *also* after exporting.

Even while watching frame by frame, the clip flickers (light/dim) as if it were an intentional effect, always flickering the exact same way, like it's embedded. In a single frame, the top half of the image might be lighter or dimmer than the bottom half, as an example, and that frame always looks like this any time I go back to it. Each frame's flicker remains the same.  If I remove an effect from the clip in question, the flickering might go away, but it's not consistent as to which effect to remove. This won't work. In fact, I'd like to keep my effects in tact.

I'm not bogging it down with effects, either. This clip has only 4 effects added to it. Not only that, but if the clip in question is sharing the screen with another clip using similar effects, it will cause the other clip to flicker, as well. They do not flicker in sync with one another, either. Both clips are fine without any flickering during the entire first half of the video.

All original video formats are 1080p

    Having the same issue, two separate machines too. Luckily on the iMac it worked when restarting Premiere, but the Macbook (2015) just can't shake it. I've deleted previews, re-rendered previews, tried different export settings (of course trying to leave the previews out) to no avail.

    Edit: Managed to find a precarious work-around.

    1. I nested the problematic footage.

    2. Removed the adjustment layer (levels to darken in my case) above them and then exported as ProRes 422. Luckily it worked just fine.

    3. Put that ProRes file into my sequence, and apply the effects directly instead of the adjustment layer. I had a text layer above that still worked fine.

    4. It exported without issue this time around.

    Do the clips flicker if you open them up in the source monitor/if you disable all the effects does the flickering go away

    Hi! Yes, it happens in the source monitor. And as previously stated: "...my problem occurs during editing in preview and remains an issue *also* after exporting." And "If I remove an effect from the clip in question, the flickering might go away, but it's not consistent as to which effect to remove." So, of course it goes away when they're all removed.

    There is no need to get snappy. I am just trying to ask follow up questions to help you. So, just for sake of science, try adding an adjustment layer over a clip that flickers, turn off all the effects on the physical clip and then put them on the adjustment layer. See if that causes it to flicker still. And maybe try enabling the effects one at a time and see if it is a consistent effect that causes the flickering

    And speaking of being thorough, I should also add that if the one clip causing the second clip (with similar effects) to flicker while they're sharing the screen - also share the screen with two more clips (imagine 4 clips in a grid, Brady Bunch style, but only 4 rectangles instead of 9 squares), those two clips continue to flicker, but the other two do not.
