Windows drawing so slow?

I have a form with a handfull of controls on maybe 10, you can actually see it drawing one by one and takes a good 1/2 second to render?
Is this normal - only just moved to windows from Mac.

10 controls? No it shouldn’t take that long.

Are you able to post a video of it happening?

Do you have some recursion in a paint (or similar) event on one of the controls or some long running processing in a paint event?

will see if i can find a way to post it here
