Also, from private discussion with Amin, this is reproduced on Ubuntu 22.04 (but not on 24.04) and with/without Snap package

I can repro something similar on KWin (flickering / mispositioned menus) with the RTL locale if the menus are large and we use the move-to-rect movement. I think we get the anchor gravity wrong for RTL, but not sure if that'd be enough to fix ^
