GNOME, default
environment.

I'm using the system's default terminal emulator. gnome-terminal? I'm not sure what it's called.
The other terminal simulator, Terminator, doesn't seem to have this problem, I haven't tested it too much.
In order to ensure the validity of the test results, I restart the system before each test.

Yes，It's still being updated. The window size will change, but it's a bit delayed.
The original description may not be accurate, the mouse can be moved, you can open a new TAB of this window,
but you can not operate other places, such as the system toolbar, otherwise the GUI will be completely unresponsive.

Sometimes this happens when you drag the right scrollbar of QtCreator. Using the mouse wheel to scroll the QtCreator window does not cause this problem
These problems are obvious when the system starts up and seem less likely to occur after a while of use or after a while of waiting.
A similar problem has occurred in Thunderbird, which happened unintentionally. I don’t use too many programs.
I use VMware virtual machine on Win10, which may also be related to the hardware environment.
I recorded the whole process in a GIF animation, the file is about 1.8MB, if necessary, I can provide.

So the terminal window's contents are still updating at this point? Is the window still at the original size?

I'd be interested in more examples, I've been unable to reproduce this so far.
