I have installed the DE on top of Ubuntu Budgie 20.10 today following the instructions here.
After rebooting and updating/ upgrading I still get some erroneous behaviour: the icons in the launcher are unresponsive and I have to add the icons to the menu bar in order to launch an application. When I click on the top left and right corner icons inside the launcher, it simply closes and does not resize.
The launcher itself won't open after this and I have to change the mode to regain control. Any idea why this happens and what I can do?
