Rotating the brush introduces (semi-)transparent pixels, which show black especially over the white quarters.
I tried all ways, hard edge brush, anti-aliased brush, all the precisions, all the modes, without success.
Thanks to have tried Rich. (also @programmer_ceds, thanks a lot for your inputs)
I think, that's not the same bug (I think), he got white problem when rotating picture AND exporting jpg,
for this one we do not need to rotate the brush to see the black, but yes when rotating the brush it's way-way worse.
I did tried with GIMP back to 2.10.12 (.13 appimage) bug was there already...
I'm gonna fill a bug report tomorrow
