When the system changes its theme from Light to Dark or vice versa, the browser gets stuck on the last possible theme (when the Opera Themes were changed), and many texts, especially when opening a new tab, it becomes almost invisible and difficult to read. Complained many times and received multiple updates, but there is no fix for it. For reference attaching the screenshot.

@leocg GX, happening after the last update

YouTube is showing bigger thumbnails, majorly in the suggested video list besides Video Playback

The problem is having especially in the browser as I have tried it in Edge and Chrome the problem was not there. I have tried disabling extensions and multiple restarts but no help.

@annoyed-at-updates have you received any solution to that or complained to the opera team
