Hey guys I'm honestly at a loss right now. About two days ago Artifacts and lines started to show up on videos and images while editing on Adobe Premiere and Lightroom. At first, I thought it was a GPU issue so I tried (a. reinstalling drivers, b. installing older drivers c. Switching between CUDA and software rendering in premiere)
Then I realized that these artifacts only happen on certain videos and clips furthermore these glitches only happen in these two apps and not VLC or other players. Certain clips shot on my A7sIII have glitches and None of the clips from my A7rIV have any issues. The clips playback perfectly when I am using a proxy version of it but as soon as I switch to the actual file it starts to happen. (I've also tried opening other projects as well as new projects and the issue still occurs) (seems to be happening on only 10bit videos but some videos in 10bit are fine)
Thinking it might be an SSD issue I transferred the files into another SSD and the issue still persists. Then I tried installing a separate (fresh) Windows OS and opening these files up again and on Premiere Pro the glitching still happens. HOWEVER on lightroom the glitching on images no longer happens which is odd. I also tried opening the same files on another computer from work and the files play back perfectly.
I have no idea what else I should do to resolve this issue and I'm open to any suggestions. Thank you for your time!
TLDR: Artifacts in Videos and Images only from my editing computer.
List of things I've done to troubleshoot this issue
Reinstall Nivida Drivers (Fresh Install)
Install Game Ready Drivers (originally Studio Drivers)
Install older Nivida Drivers
Dialed back Overclock settings
Disabled any Overclocks
Reinstall Adobe Suite (all adobe apps)
Installed older version of Apps
Movies files to a different SSD
Deleted Video Previews as well as Caches for Premiere Projects
Changed Premiere Pro Renderer
Changed Lightroom Graphics Acceleration
Created new Premiere Pro project with [8k,4k,1080p] at [16bit, 10bit, 8bit] in H.264 and H.265
It seems like none of the 8bit h.264 files are affected (Sony A7Riv)
All files that have the glitching are from 16/10bit videos (Sony A7sIII, FX6)
Not all files from my (Sony A7sIII and Fx6) have the same glitching issue
Installed separate windows 10 OS partition to see if the issue is resolved
Lightroom Lines and Artifacts don't appear in new windows install
Premiere Pro glitches still happen
Used separate PC to playback files and all of them playback perfectly
Hate to be the bearer of bad news, but I think your GPU is giving out. I've seen these issues in that scenario several times, and since you've tested on another machine and it works and you've gone through all the troubleshooting steps I would typically recommend, all I can think is that the GPU is throwing errors under extreme circumstances, so with easier 8-bit footage it doesn't show up, but when playing back 10-bit footage in an editing application, it's maxing out and causing these artifacts.
I'd recommend replacing the GPU (check if it's still under warranty), or transcode the footage to another format like ProRes that doesn't throw those errors for the meantime.
