Gnome shell using 100% per core CPU and freezing when opening unity project

When I try to open a project in unity, gnome shell completely freezes. I managed to open a tty and run btop. there I saw that once the opening starts gnome shell starts to use 100% CPU on one core. unity barely uses any recourses at all and memory is normal. after the loading has finished everything returns back to normal.

is this a bug, and should I report this?
