Sequence preview images/thumbnails flicker in some project bins

Hey,

I have a super annoying issue with one project I'm currently working in, where preview images of sequences start to flicker. 

I usually sort my footage in separate sequences so I can merge separate audio tracks more easily, thus I have a lot of different bins with short sequences.

Now I have one bin that gets super flacky - see video. In Premiere Pro 2025 this happens by itself and gets triggered by setting an in or out point in the sequence. Then the whole program becomes very laggy and starting any videoplayback freezes the playback handle etc.

This clip is recorded in the latest Premiere Pro Beta 25.2.0 Build 12, in which similar strangeness happens, except the program still functions without restarting. I remember that this bin had the same issue in the last Premiere Pro 2024 version.

I already imported everything into a new project which didn't help. For some reason it only happens in some bins and not in others. The one showing the issue has 176 sequences in it. I have another one in the same project with 246 sequences, which just works as expected. (only the top left one flickers when scrolling, but it doesn't keep doing it). When another bin is opened for longer, and you switch back to the bin with issues - it stops the flickering for a while.

Is this an issue with my hardware or with Premiere Pro? Cause I pretty often have display artefacts in the playback window and sometimes on the thumbnails (small blocks of fully saturated colors or grey in a regular pattern that quickly changes and than disappears). Or is maybe the bin itself corrupted in some way?

My current hardware:
Intel i9 13900K (non OC, with Intel limits)

128 GB DDR5 5200 RAM

Nvidia RTX 3080 12GB

Premiere caches on a separate NVMe Drive and the project data is stored on a 8TB Sata SSD Raid 0

The footage I work with is NLOG 4Kp25, p50, p100 and sometimes 8Kp25.

Thank you for your help. This seems super puzzling.
