Screen bugs out when I exit an app and return to the home screen

There’s been worse than this, sometimes it really takes a while to return to normal. As well the Calender doesn’t want to seem to work. Like I’ll tap on a date or try to see the next month and it won’t do anything. And the notification alerts don’t want to pop up either. I did edit this a bit but really only to change the colors of the tabs. Maybe I did something else to it by doing that, I don’t know, I am really new to this so maybe i just didnt code it right. I have a Samsung Galaxy S23 Ultra, I’m running the free version of Nova7, and the version of KLWP is 3.74

Go to KLWP’s app settings >> Advanced options >> Turn on “Disable Parallel Rendering”.
