I am a new cursor user. I have been using cursor about a week. I have noticed that my laptop fan is often running on high speed now for long time intervals. When I checked to see what processes were using so much CPU it was cursor. Then I was surprised to find many cursor processes running simultaneously, and some even appeared to be different versions of cursor. I have noticed that cursor upgrades itself, but hadn’t realized that all of these processes were being started and left running. I exited the cursor app and found that all of the processes listed below were continuing to run using high CPU after I had exited the app. Why are there so many of these processes running and why are they using so much CPU? The processes seem to fall into two types: 1. Processes with build in the name: vm:~$ ps -ef | grep cursor | grep -v .mount howard 2167 1039 0 01:05 ? 00:00:03 ./cursor-0.30.4-build-240325dezy8ziab-x86\_64.AppImage howard 13954 1039 0 07:41 ? 00:00:01 ./cursor-0.30.5-build-240327tmd2ozdc7-x86\_64.AppImage 2. Processes with /tmp/.mount\_cursor in the name. There were many more of these types of processes running: oward@howard-fltv-vm:~$ ps -ef | grep cursor howard 2162 1039 94 01:05 ? 15:00:52 /tmp/.mount\_cursor9iIzpO/cursor howard 2167 1039 0 01:05 ?
