On my pc (regular i5), I get noticeable delay (0.2 …0.7 s) after esc hit. I remember having this problem at higher extend when doing real project, but someday it was gone. This is related to specific project or configuration, probably…
I tried to open pcb editor and 3d viewer, set option “refresh 3d view automatically”, but this seems not to be crossprobing related, no delay change.
Could you try to open your project on faster pc, or with default kicad configuration (temporaly rename kicad settings folder in your %appdata% folder), or upload your project here for testing?
Well, you’re right: my schematic contains ~350 components and KiCAD behavior is really terrible. Whe I tried scheematic with up to ~50 components it is OK and ~0,5sec delay is present, but still not annoying. But if there are more than 150…200 components, then it starts to be exasperating O_o
Well, I confirm this with my project (larger one). Revert from ESC takes 10 seconds…:
I will search for big project in github to be shareable and report this to bug tracker. Now I understand how this problem magically disappeared - just not working on that bigger project anymore
