Thumbnails for large image files not displaying in project bins if GPU enabled

[jhbradley610]

Premiere Pro v23.1.0 on Win 10 21H2

The images are large (4k x 4k ish), non transparent PNG files. Importing them into the project (via File Explorer, or the Media Browser) results in blank thumnail images, unless I set the Mercury Playback Engine to software only mode. Which is a non-starter; obviously I want to use GPU acceleration.

I have the current nVidia drivers installed (528.02) for my GeForce 1060.

This is not an issue in v22.6.3. I can load the same exact images there, on the same machine, with GPU acceleration enabled, and the thumbnails display perfectly fine.

Also, smaller images (1920x1080) work correctly in v23.

FWIW, it seems to be related to file size rather than image dimensions, possibly. I took one of the PNGs (3668x3668 18MB) and converted it to JPG in Photoshop (3668x3668 7MB). v23 correctly generated the thumbnail for the JPG.

I have a simple high res PNG (3840x3024 213KB) - that also produces a correct thumbnail in v23.

Just updated to Premiere Pro 23.2.0.

Still broken.

A pity; I'd like to use the current version at some point, but as I regularly assemble videos from large stills (think Ken Burns), not being able to see thumbnails of same is a debilitating bug.

Update your NVIDIA driver to the 528.49 Studio Driver:

Good guess - I hadn't noticed the existence of 'Studio' drivers.

But no. Installed 528.49, did a clean install just in case any of my settings were 'wrong' - exact same behavior. Large PNG files don't render thumbnails. Large JPGs and PSDs do. The aforementioned PNGs are generated by the current Photoshop, fwiw.

Premiere v22 (22.6.4) has zero problems in this regard. Thumbnails for all file types are rendered quickly and correctly.

Here's an example of one of the PNGs that does not thumbnail-ify in v23. At least on my system. Curious if it's a general issue or a 'me' issue.

I always resave png as psd in Photoshop before importing into Premiere Pro.
