Export to JPEG gives weird colours in 9.1.2

I have just upgraded to C1 Pro 9 after using Another RAW Converter for a while - ran a batch of images through to check it out, and I'm getting really weird colours when I export to JPEG:

it looks like some sort of gamut or exposure warning is being exported, but the image has no out-of-range areas - here's a screenshot of the same image inside Capture One:

I have tried exporting to JPEG (quality level 80, sRGB) and also to TIFF - same result.

The files are from a Canon 5D Mk3, and that seems to be the common denominator - files from a Fuji X-E2 export with no problems.

It doesn't make any difference whether the Canon 5D Mk3 profile or the "Generic" profile is selected in the "Base Characteristics" section.

Can anyone help?

Update: I removed V 9.1.2 and tried V 9.1 - same problem.

And now I can't launch version 8 either, it crashes and quits immediately on launch.

I remembered a thread with similar problems. Are you by any chance using an Nvidia GTX980 graphics card on a MacPro? See here: viewtopic.php?f=61&t=22218

Thank you, yes I found that thread and it seems this is my problem - I am using a Mac with a GeForce GTX970 card by EVGA - it's sold for Windows computers but there are official NVidia Mac drivers for it, which are up to date.

I am running El Capitan (OS X 10.11.5).

I found that disabling Open CL for processing gets rid of the magenta overlay problem - but that's not really a solution as Capture One should be able to use the graphics card via Open CL.

I use the full Adobe CC suite as well and don't have any problems with the graphics in those applications or any other program - just Capture One.
