Gigantic right click menus. Even if font size is set back to smaller font sizes. Even if the new "display" option is not selected and "light" or "dark" are chosen instead. Something to do with Zenity? No clue.

Anyway, don't click on Use Classic or Use GTK or Use QT etc in Settings. (the OTHER other settings)

The latest Vivaldi Stable will hang if you try that.

To get out, just quit even if the program is still running. Then use Synaptic Force Version to re-install the previous version.

Then re-install the latest version if you want to keep using the latest version.

That restores the setting back to a functional original. After that, DON'T CLICK! :)

Just gonna have to live with the gigantic menus until they're fixed. *hopeful*
