1. It sounds like there's a problem with the HDMI connection. Do you only see problems on the HDMI display? Sounds like there's a problem with the "GSM" (LG) display.

[ 647.746] (WW) EDID timing clock 328.32 exceeds claimed max 175MHz, fixing

2. Please attach a photo of the problem.

3. Please try selecting 'Ubuntu on Wayland' from the login screen. Does that avoid the problem?
