Hi Jelle,

sorry that you experience this slowdown.

Those kind of bugs are very hard to triage, so we'll need more
information.

What is your Desktop environment? Are you using Wayland or XOrg?

When started from console, is there messages there?

What is your GPU?

When you are using Wayland, how are you starting freecad?
(because of #1051296, the workaround there might have impact on
performance)

Can you reproduce it when starting freecad with:
   QT_QPA_PLATFORM=xcb freecad
