Pic in pic and split screen cause unusable latency and stuttering

[sloppy]

Greetings all,

I am hoping some wise soul can help me out.

I am having a persistent and new issue when editing using picture in picture or split screen (2 or more videos in frame). I used to be able to use this feature without any issues, as of a few days ago and for reasons I cannot determine, adding more than one video in the frame cause a massive amount of latency and stuttering of both video and audio tracks. I thought doubling the memory would certainly help, but it had zero effect. As of now it is totally unusable. Specs of the laptop are below. I am HOPING its some setting I unknowingly changed? That doesnt seem likely, as I removed and reinstalled shotcut hoping that would help. It didnt.

Any help would be greatly appreciated.

Are there any other applications running that could be taking resources?
