To test, turn off graphics acceleration in your Lightroom preferences->Performance tab. This looks like a problem with the video card driver. If that helps, See if the manufacturer ofyour video card has an update for the video card driver. Install that and test with acceleration again.
Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
