Still no update to solve this issue?! Come ON Adobe!! Why is this still happening in PP2022???? I have been having this issue on two different computers for well over a year now. Why is this taking so long to fix? Right now, I'm trying to go through a 2 hour, single camera, piece of work and have to go through it in real time because every time I tap the L key to increase the speed, the video freezes and the audio starts jumping around and I loose all control until it finally crashes and closes after a minute or two. Extremely frustrating!!!! Adobe...Where are you on this??????

Still having this issue. Is there any permanent fix?

There is somewhat of a temporary fix. Instead of scrubbing through with your mouse, scrubbing through with the arrows on your keyboard works fine. You can also hold down shift and arrow to make the process faster.

Same issue on Windows 10 (17763) on PP 2020 14.7.0 (Build 23) - but ONLY if I'm sending the output to an AJA Kona LHi.

Spacebar playback results in massively delayed (or completely frozen) playback in the program of Cineform proxy files in the Program panel. Scrubbing left to right with the mouse (frame by frame) does work, however.

I've recently upgraded to the iMac Pro and have modified everything to almost max when it comes to the graphics card, RAM, etc... expecting it to solve all my scrubbing and lagging issues. It's exactly the same as my previous iMac and I don't understand what's going on. All the editors I know tell me they don't face any issues like this but I have been struggling with this type of slow and frustrating issues for years with Premiere.
Has anybody found a solution yet? Is it something I am doing wrong with my settings?
Even when I create proxies Cineform or H.264 it makes no differences.

Solve it!!! Go to Sequence Setting- and change Timebase until it works. For me if i go from 50p-25p the value is 23.97

the most basic funcion of video editing.. not possible..

well done Adobe!

Why hasn't this been fixed yet?! This is such a huge waste of time

Has anyone found a good solution to this?

I'm having a scrubbing issue (though, maybe not exactly as OP stated) but it's when I'm scrubbing through footage in icon view (not main timeline) and only after I've inserted a selection from that clip into my main timeline. Then, once I start scrubbing (not hover scrubbing) I'll start to see other parts of that clip and it only stops when I slow down a lot or stop scrubbing. It seems it's jumping to my first in I created while culling that clip.

I'm having the same issue as David. When interpreted footage, say from going 60fps to 24fps timeline, when I move forward or backwards frame by frame, every other frame shows a completely different section of the clip. This makes it very difficult to do edits like keyframe tracking. This doesn't happen with previous version of Premiere

I believe I have found somewhat of a solution for this issue, I have been dealing with it for awhile as well. For me, when the playback keeps jumping around while scrubbing footage ive interpreted from 120 to 24, I have found that rendering the clip twice eliminates this issue.

I have a brand new 2020 iMac with 32gb RAM, solid graphics card and a fast processor. The hardware is definitely not the issue here. However, after rendering the first time, the clip will usually show a yellow line above the clip, and then green after the second render. At this point, the scrubbing issue goes away.

Hopefully this is just a bug that can be addressed, but for now, this seems to work.

Version 14.3.0 Build 38. I'm having the same issue with scrubbing.
Time Remapping is a complete nightmare.
I'm having to Render after each speed ramp adjustment in order to view the clip.

I'm having a scrubbing issue with the latest version of 2020 as well. But it's after I interpret footage, the clip no longer displays properly. When scrubbing through the clip it shows the incorrect portion of the clip, and when speed ramping the footage completely goes haywire, then I have to delete and reimport.
