Output: Use dedicated Rectangle for panel orientation indicator
My clever EPSILON hack seems to no work reliably enough in certain screen resolutions and scales. Use two Rectangles again, one for the panel and one to make its top corners square again.
No longer have a weird gradient. Didn’t test with multi screen though.
I know Qt 6.7 has API for individual corner but it’s marked as tech preview and I want this backported to 6.0
