Hi, I have a problem since upgrade to Opera 86.X.
Usage of CPU is very high, almost 50% for couple of minutes, can be reproduced when you open more windows with plenty of tabs (e. .g. currently opened 10 windows, each window in average 5 tabs) and starts typing in the URL address bar (probably issue regarding changes of the URL bar).
Tested without any extensions, the biggest consumption is done by the "Background worker".
Pretty annoying and expensive...
When I downgrade to Opera 85.0.4341.75, everything is OK.
I have also reported a bug, however, nobody has answered yet.
