Bug report: Generated proxy media is faulty

Hi all.
I mainly use DR for timelapse.
Source is .jpg images, 7360x4912 pixels.
Playback in editor is horrible, render cache throws "GPU memory full" all the time.
Final render takes hours for a 1 minute clip and often fails (GPU memory full).
Therefore i want to use proxy media in original resolution, so i can use it as a source in the final render to speed things up.

The generated proxy media is indeed 7360x4912, but the source images only fill a tiny spot in the center.

It looks the same played in VLC.

If I crop the images to 16:9 format and save them with 3840x2160 resolution, proxy media files ar fine.
If I just crop to 16:9 and save them with 7360x4140, the problem occurs again.

Here's a link to source images and generated proxy media.

Please fix this. DR is unusable now for creating timelapses with source images with resolution larger than 4k.

Best regards,
Lage

Diagnostic log archive.

A response from developers explaining this would be appreciated.

Support have looked at the limited logs. Unfortunately there seems to be no log archive but from what is shown, the GPU memory is tapped out, not surprisingly for a 4GB ram and a 8K source image. i doubt cache will help as the image still needs to be processed from the 8k and with just 1024 CUDA cores its quite underpowered for 8k too.

I'd suggest a GPU update is needed.
