      I've been using Opera GX for over a year. Recently, I noticed that my selected color themes no longer display properly. The menus seem to display the color theme correctly, but the Opera GX window and tabs do not. Additionally, I am unable to install new themes from the Chrome store (which I used to be able to do in Opera GX). Now, when I attempt to install any theme from that store, I see an error message stating "Download Error: invalid manifest." I tried resetting my Opera GX browser to its original settings, and that didn't help. I then even tried uninstalling/deleting the app, then reinstalling the latest version. Same issues still persist.

      For some context, I'm using a 2019 iMac (intel chip), which is currently running Sonoma 14.4.1. Here's a screenshot showing the theme issue - as you can see, the menu on the right is displaying the correct theme, whereas the main Opera window is not.
