Starting Vivaldi in Ubuntu 22.04.02 quickly generates 60.000 lines of (I suppose) error messages before ctrl-C. The first one is Cloud management controller initializations aborted as CBCM is not enabled. "CBCM" defies my internet search. The second message is [6578:6578:0729/171213.906249:ERROR:shared_context_state.cc(81)] Skia shader compilation error.
Small bits of the start page are rendered, but really nothing useful.
There have been problems for a while, but up to fairly recently Vivaldi has basically worked. For a while startup problems could be solved by creating a new window, but no more.
Unfortunately I don't know which Vivaldi version I'm attempting to run since it never gets functional enough.
I have unsuccessfully tried "vivaldi-stable" with "-disable-extensions" and "-no-sandbox".
I also saw a recommendation to turn hardware acceleration off. Great, but how? The browser is not functional.
Chromium and Firefox run on the same box without problems.
EDIT: The package is vivaldi-stable 6.1.3035.204-1 amd64.
