Weird glitchy boot load screen problem, how to fix it?

[jollygreen68]

I've got this super weird glitchy screen that pops up a few times during the boot up process on my Linux machine. It's Kubuntu 24.04.1 LTS with Plasma 5.27. I have a Grub theme installed, this one. And every time I turn my computer on, this crazy glitch screen shows up multiple times in the boot process.

So I choose Kubuntu from the Grub Boot Menu (this is just a stock photo of the Grub Theme, not my actual Grub Boot Menu) and then this weird a$$ glitchy screen pops up and stays there for about 2-3 secs, then my Motherboard BIOS screen comes up with the Kubuntu logo at the bottom for about 1 sec, then this crazy screen comes back up again for like 5-7 secs, then finally Orchis Splash screen, then my Plasma Theme Log In screen. It also shows up when I logout or restart or shut down. What is it? Why is it there? And how do I get rid of it?
