Jolla Homepage flickers everywhere

OS: Fedora
Browser: Vivaldi 4.0.2312.27 (Stable channel) stable (64-Bit)
Bug: Website flickers
Description: Only Mainpage flickers. following Sites are ok:

Info: In Firefox the Mainpage is ok.

You have an out of date Vivaldi version 4.2 (2406.54) is the latest, try that one first.

Can not confirm this with Vivaldi versions

3.6.2165.40 (Stable channel) (64-bit)
3.7.2218.45 (Stable channel) (64-bit)
Windows 10 OS Version 1909 (Build 18363.1801)

Yes, my version is not the latest, but I don’t know any website with errors and I surf a lot on the computer. And so far the site has been fine.
Ok, maybe I am an isolated case.
