LUTS blacking out screen in DR17b8

Hi, I've had a search but can't find this mentioned.

Since upgrading to DR17 all luts are almost completely blacking out the image. There is a hint of the original image barely visible but nothing useable and the graphs all sit right at the bottom.
different luts do have a different hue so they are being applied, but not interacting properly.

Same LUTS as I used on DR 16 without issue, and I've tried installing a new LUT pack and that's acting the same.

I've also updated to the latest DR17 version since having the problem and the update did not solve it.

h.264 footage optimize to DNxHR SQ which is again the same as I used regularly on DR16

anything? any ideas?

Native LUTS as well, or just third-party LUTS?

Where are the LUTS being applied?

What are your Color Management settings?

All LUTS, native and third party.

Davinvi YRGB
rec.709 Gamma 2.4

media is all generic .mp4 h264

I don't think any of my settings have changed since DR16 and all the rest of the project and the exports work fine

OK.

I can't duplicate this in Studio 17b9 for Windows. I tried several LUTS from different categories and they all worked fine.

So that's leading us towards a GPU or driver issue on your system as something to check.

What model card? What driver version?

I'm aware its not on the higher end of PC specs but as I say I've not had any of these issues previously.
