eeschema has also become very slow. Any action - freezing for ~4 seconds.
Profiling: calls to recalculate connections in OnModify().
“IncrementalConnectivity=1” in kicad_advanced doesn’t help.
Ryzen 9 6900HX, 64GB
build kicad with -DPROFILE and adding some timers to source
Add profilng DoDelete() and OnModify() in sch_edit_frame.cpp
