Bug no Blender

Boa noite, o Blender apresentar travamento para varias ferramentas, exemplo… multiresolution
trava usando 20% do computador

Try to run the program with various debug command line parameters to see if there is something mentioned in the logs.

Another idea is to consider to backup your Blender user profile settings, and then deleting it, just to make sure that no addon or configuration brings the problem. It could be any addon running with a modal operator that hogs up the cpu.

Another idea is to installing Blender in a fresh machine (USB bootable \ Virtual Machine) just to exclude the case that any third party software messing with your program (it could be a virus - who knows).
