After updating to 14.9 from 14.2 I noticed some weird graphical glitches in the timeline. You can see an example in the attached video. Is there anything I could do about it? Have you experienced it too? My gpu drivers are up to date and I'm using the game ready drivers from nvidia.
Always clear media cache after any of Premiere Pro/Media Encoder/GPUdriver updates:
Preferences > Media Cache => Delete all media cache files..
Or you can do it manually - close Adobe PP/AME/AE, goto media cache location and delete folders:
Media Cache, Media Cache Files, PTX, Peak Files.
Do same with workspace, reset: Window > Workspaces > Reset to saved layout
It does not fix the issue. I also tried a clean reinstall of premiere and that did not help either.
I believe you should do a clean install of the latest STUDIO driver and not use the game ready drivers. It's never a bad idea to delete the cache per @basil1891 comment. I do for every upgrade.
Delete your cache files as follows.
The files are located here: Paste the whole line into File Explorer.
I just delete the three folders:
Media Cache Files
Sadly, the glitches are still present after doing all of these things.
I've just downgraded to the 14.8 version and the glitches have disappeared. Is there any way to send a "bug report" or something like that to Adobe? I couldn't even find a regular support contact like an email on their website. Are these forums the only way?
Just wanted to chime in to say that I am experiencing this issue as well. It's quite distracting when doing a lot of timeline adjustments with snap enabled.
I first noticed this in 14.9 on two different systems, each with a different studio driver from Nvidia (both were recent drivers - one was the latest and the other was a couple releases back). I've since tested Premiere 15 on one of the systems and the issue is still present.
I'm sorry that you have the same issue but it is good to hear that I am not alone. I was told that it is a problem with my GPU and my system but I do not believe that as it doesn't happen on any version prior to 14.9. NVidia support also confirmed that it is NOT a GPU problem, nor a driver problem. It is mostly a "minor" visual thing but it gets quite annoying after some time and especially when the audio layer shows a waveform when there is none.
