Hi Tobi,I checked again with the Flatpak version of FreeCAD 1.02. It seems a lot faster with repositioning the dimensions. But when recalculating the sketch and Body. It still takes a while. I guess one of the bug-fixes for 1.0.2 introduced this optimisation.
The problem also persists when testing on X11. (I see no mention of Wayland when starting FreeCAD under IceWM window manager.)
I think it would be fine to keep this open with the fixed 1.0.2 indication.
best regards, Jelle
