I draw a square with 40 x 40 mm.
I apply the distortion tool Arc to it and set it to 100%. After that, as expected, a clean semi-circular arc should emerge. Unfortunately, however, there is a small gap on both outer sides.
If I create two arcs and rotate one by 180 degrees, I should get a perfect circle of 120 mm. Unfortunately, when I place a clean circle on top of this construction, the two arcs are not congruent. I have attached an example file in the appendix, where it becomes clear.
I am using the latest version of Affinity Designer.
The bug can be reproduced at any time.
My computer is a MacBook Air M1 (2020, 16GB) with OS Monterey 12.6.
Hardware acceleration is on, the bug is independent of that.
