cursor keeps freezing for 3or 4 seconds

I just installed Endeavor os ( kde DE) on a system 76 thelio mira. everything seems to be running just fine but the cursor will freeze for 3or 4 seconds every couple of minutes. I have tried the following troubleshooting things
tried 4 different mice and all do the same thing. they all work just fine on my laptop ( linux mint) =- so i don’t think its the mice.
when i ran pop os on the desktop there was no issue either
i tried using different cursors from the available choices in plasma. so far they all do the same thing.
mouse driver issue?
commands to re-install the mouse driver?
