Problem description:
I have a perfectly working Xbian setup running on Raspberry Pi 3B+. I bought a Raspberry pi 5 and a new microHDMI cable and PSU to go with it and did a fresh install to import my home directory but I have the same problem the user here is having. The rainbow boot screen, text, Xbian splash screen and Kodi Nexus startup animation all play perfect, but once I get to the actual Kodi UI and set up wizard, the visuals are glitched: There is no text anywhere but the UI elements otherwise seem to be there. There are also some unclear vertical columns in the blue background color. Transferring the xbian-home-backup file didn't solve the issue.

Everything else works: SSH, CEC etc. but the Kodi UI is unusable. I tried both 32 and 64 bit versions of Xbian, even LibreELEC but it had the same problem. I tried Retropie and Raspberry pi OS and they both work perfect and my TV works with Rasperry Pi 3B+ Xbian.

The problem is already fixed in an OpenELEC nightly build from around the christmastime of 2024, linked in the Kodi forum post above. I tried a nightly build of OpenELEC and I'm watching a movie with it as I'm typing this. I don't know what fix or settings change is implemented there, but I hope it's also coming to XBian.

How to reproduce:
Get a Raspberry Pi 5, install latest Xbian and hope for the worst.
