A combined delegate for read and modify could be worked out (signals etc.) but for ease right now.

Now it's even worse on MacOS....

Now it's even worse on MacOS....

So it's an extra tick but is the tick also a bit larger too?

I was wondering if PyQt6 is going to make any difference to this at all but I don't think it will.

IIRC the problem was only on Linux (I'll check), so I think it's possible to do this change only for Linux.

Try this. It looks like the "tick" was being drawn twice (didn't notice because it was perfectly aligned) so I've removed the draw from the code here.

Now I don't get any visible check on MacOS and It crashed when I clicked on the 'Write Tags' checkbox too much

Try this. If not then skipping it on MacOS might be the option. I did wonder about the purpose of if platform != "darwin": and so left it in. I thought it might only draw the tick but the whole check box was missing?

Not too sure on the None as it shouldn't be related but let's see if it goes away once the box is drawn again.

By default on MacOS it only has a tick. There is no checkbox

In the double tick screenshot you gave above; is the box there not usually there?

Does this just draw a box and the tick or just the box? Any harm in having the boxes?

If there's still a problem: Because I can't try different solution, if I put in some different options commented out so you can try them, is that okay?

Sure

It looks like you can reset to a44e037 and then you just need to remove the extra import platform

I've reset and removed the double import. Is that original one now working (with the PyQt5 5.15.11 update)?

If not, I'll push the other options.

It works on MacOS now
