I downloaded blender 2.8 a couple of weeks ago and it was working fine. Yesterday, the interface became so laggy. I'm not able to spot the issue because I didn't install a new software or something like that. Maybe I tried to install Quick Functions and Power Sequencer addons but I deleted them and the issue still presists. I also tried to load factory settings and other things but no avail.
