More Windows on ARM C1 results
Well the news is not so good this time...
I've done a couple of posts around the fact that C1 works on Windows on ARM, and the performance is pretty good given its not native. However I've now found an area that is definitely not working as designed, and that's the AI brushes.
I have a simple picture of the beach, water, an island, and the sky. If I use my I7 desktop, and click on the AI brush, it almost immediately highlights whichever of those elements the mouse is over. Clicking selects that element. If I use the Yoga (ARM PC), then when I click on the AI brush, I get a small pause while it calculates the AI mask, but the mask ends up spread over the entire picture, and looks like some kind of square lacework, which is incomplete in parts.
By contrast the magic brush works flawlessly as always. I'll raise a bug report later today...

Ignore that. I found out if I regenerated the preview, the problem goes away. Sigh. I guess this means I need to regenerate all previews. At least its fast on this device.

Yeah me too. And if they worked on implementing the AI portions using the new AI chips....

Sigh. It looks like there is definitely still a bug here. I've had a few photos where the AI mask seems to work, but most of them fail with the lace like highlights, and inconsistent generation of the mask. Very frustrating. I'll put in that bug report tomorrow.

Some further testing shows this is all to do with the preview. When you edit a photo at anything less than the size of your previews, C1 does not reference the original at all, it uses the Preview. If you are using the AI brush at this zoom level that does not work properly on a Windows on ARM device. However, if you zoom in to 100% and use the AI brush on the same photo it works perfectly, because at this zoom level C1 uses the original file.

This is great info. I hope you will provide it to Capture One in a support case.

Some further results (positive this time). I do most of my editing directly on my laptop, but I do also edit on the widescreen monitor I use for work. As a result, I had set my previews to 4K resolution, and its these previews that were causing problems with the AI Smartbrush. I wrote above how when you zoom in to 100% (when C1 will use the photo directly, and ignore the preview), it all works.
Anyway, last night I changed my preview generation size to 2880 and regenerated a couple of years of photos. Now when I try to use the AI brush on these photos they also work perfectly. So, it looks like the problem only occurs at these higher preview sizes. I'll probably do some more tests, but I will go ahead and raise a support case to C1 about this.
