September 16 Windows decided to install three updates while I was powering off my computer that night.
I’ve been working on a fairly big video with lots of clips and sound. Approximately 35 minute long video. Wich have worked out good when I have edited long videos before. Never had major problems.
The very next day I continued to work on the video but everything soon came to an halt. Everything was so sluggish. Shotcut crashed all the time and I could not get anything done.
So I tried to start another project with just a couple of videofiles. Same issue occured. Sluggish and impossible to work with.
I then tried to edit with proxies and even then it was sluggish. To such an extend that it was almost impossible to work with.
I decided to upgrade from 16 to 32 gig of RAM. Same problem. So I knew it could not be hardware related. Atleast the RAM. My CPU is Intel(R) Core™ i7-8650U CPU @ 1.90GHz 2.11 GHz
GPU is Intel UHD Graphics 620. Computer is a HP Elitebook 840 G5.
Then after trial and error trying to disable start-up-elements and different things I remembered the updates that was installed september 16.
I looked in the update log for windows and found three different updates installed that evening.
KB5030211, KB5029919 and Servicingstack 10.0.19041.3385
I first paused any updates for the next 9 days.
Then I uninstalled KB5030211. Rebooted and tried to open my project in Shotcut. No difference. Slow and sluggish.
Then I uninstalled KB5029919. Rebooted and fired up Shotcut. Everything was back to normal.
Link to the update.
