Please FIX Lumetri Color errors
The past 2 iterations of PPCC have been a disaster when attempting to use Lumetri color. When scrubbing through clips with Lumetri applied, sometimes the color will shift (in the monitor) to a completely desaturated (log-like) image ... even though my original footage was not shot in log.
When scrubbing back across, sometimes the color shifts back to the proper corrected look, but other times I simply have to toggle the fx lumetri effect on/ off to get it to return to normal.
The absolute worst part of this, is that during exports, sometimes PP will manifest that same glitch by EXPORTING a clip in the washed out look. Considering some of my projects are 6-10 minutes long, and sometimes it's just an individual random clip, this is infuriating.

Same issue exporting the project.
Am using macOS Catalina 10.15.7
Premiere Pro Version 22.2.0 (Build 128)
Media Encoder Version 22.2.0 (Build 64)
Tried several attempts w/o getting the colors corrected but have decided to delete all my Lumetri adjustments.
This issue has never came up for me until I have updated PP and ME to versions above listed

I am getting a HUGE bar of white pixel noise across every frame that I have previously colored. Is that GPU problem?
UPDATE: first and foremost, you should all go and check this thread by Matt Johnson & Adobe out https://forums.adobe.com/docs/DOC-9952
This seems to account for much of the color shift in export ... as far as the glitching in the editor, I think lots of it may be down to overloading the GPU with unrendered effects, not using proxies and other workflow remedies. I'm still looking into it.

I've just had this come up on one particular project. It's near finished and already graded w/ Lumetri and I noticed a few clips looking off when I opened it today. The clips look under exposed and more contrasty than did previously (or compared to another clip from the same interview, say). But it also changes mid-clip sometimes, looks like an exposure change at a random point as you scrub or bounce around. I've seen happen during normal playback as well, where it looks like the exposure is flickering. And it does make it's way into the final export through AME unfortunately.
Here's what I've tried, none of which has made this problem go away:
-Export sequence to a new project
-Disabling the stock input lut I had applied
-Uninstall, reinstall all adobe stuff (CC, Premiere, AE, AME)
I'm on the latest & greatest version. Just re-installed today. Will try to grab screencap of this and post later.

Yes, I have the same issue. I match from back from the timeline with color grade on a clip to the viewer, and it still shows the color in the viewer!!!
Other problems are I have the same exact interview clip, no lighting changes with the same exact color settings on both, yet they both look different?! WHY!?!?!?!
Then on export, it shifts the colors yet again! I can never figure out why, so I always have slightly different color for each clip, that has the same color, every time i export. FIX THIS. It's been in 2017, 2018, and now 2019...
