Ozone platform Wayland causes 1 minute startup delay

[CarloCattano]

Description

when using brave-browser-nightly --enable-features=UseOzonePlatform -ozone-platform=wayland
Brave takes at last +50 seconds to start.
Here is an example log of what happens during startup, and some additional bug on restore.

brave-browser-nightly --enable-features=UseOzonePlatform -ozone-platform=wayland

# 1 minute later ..
# it opens

Even on mouse move in the restored page DOM produces numerous logs like this one ad infinitum:

[41608:41636:0717/105729.028663:ERROR:shared_image_manager.cc(326)] SharedImageManager::ProduceMemory: Trying to Produce a Memory representation from a non-existent mail

[41608:416

When the restored tabs appear, chances are they are going to get obscured by mysterious dark rectangles and behave strangely with the console spamming the mentioned shared image manager errors.
the only way out is to copy the restored tab url into a fresh new tab.
