I've been using Thunderbird for a long time on this computer now and it has always worked like a charm. However, since the latest update I am unable to view my emails as the main window is mostly invisible. When I start Thunderbird, I can see how it builds the window quickly, displaying one component after another but immediately removing them again afterwards. After this process is over, the window is completely invisible and I only see a small, blue loading circle in the top left of the screen. Clicking on the Thunderbird icon in the taskbar has no effect. Sometimes single, seemingly random elements of the GUI remain visible (like for example single rows of my inbox or the "File" button in the menu bar) but disappear as soon as I point my cursor at them. It is hard to make screenshots of this phenomenon, I would probably have to provide a screen recording from when I start Thunderbird to properly showcase what the problem is. Interestingly I am sometimes able to click onto the menubar options (File, View, ...) and use the context menu, through this I was able to open my address book which functions without any problems. I feel like the program itself is starting and working as intended, however, the GUI isn't displayed correctly. As I haven't changed any settings in the last days I don't know what causes the problem. Google searches regarding the latest Thunderbird version and known GUI bugs didn't yield any results either. I use Windows 10 and should be on the latest version of Thunderbird. Any help is very much appreciated!
