DaVinci Resolve Studio (17) issue

This happens when i switch to full screen what can it be?
Dvr 17 beta 4
I'm on iMac 2020, i9, 5700xt 16gb, 64gb ram
on switching to full screen a glitch appears for a few seconds and then you see the correct frame, see attached image

I am experiencing a similar issue with a similar setup. The glitch was not present in Version 16 of Resolve.

I've uninstalled and reinstalled both Resolve and Desktop Video but the issue is still present. Does anybody know the solution to eliminate this glitch?

Post up some details, Ryan.

System, media, project settings, etc.

2017 27" iMac

macOS Big Sur
Version 11.4
Processor 4.2 GHz Quad-Core Intel Core i7
Memory 40GB 2400 MHz DDR4
Graphics Radeon Pro 580 8GB

This glitch happens with all media and all project settings. So it's not related to HD vs UHD media, etc. It does not happen in the Edit Page. It happens when opening the Color Page and when toggling Full Screen within the Color Page.

The video below captures everything that I am speaking about.

That looks like a hardware issue to me.

If my problem were hardware related why would the glitch only happen on the color page?

It looks like hardware or driver to me.

Some faults will only show up under specific conditions.

If it was me, I'd be trying some other GPU drivers. I seem to remember other people having issues with recent Resolve versions and AMD graphics drivers.
