When a form is taking some time to load due to some component in use initializing slowly, opening the form with the GUI builder may make the IDE save a snapshot. Saving that snapshot may take minutes making the IDE unusable if pushing the garbage collector heavily (-Xmx1G) although that snapshot is of no interest as the slowness detected is not related to the IDE but to the (slow) component in use. I would like to request an option to either let the user cancel the "saving snapshot" task or to let the user confirm the snapshot to be saved at all. For example: "Slowness detected. Do you want to save an IDE snapshot ? Yes|No"
Created attachment 146957 [details] Example project. Example project demonstrating the issue. Just compile the project and open the 'Panel' class with the GUI builder afterwards.
