Record your webcam with ffmpeg, and you will only see the warning or error, or whatever it is, it won’t show the time recording, the size, or anything else.
Use a different terminal, like Mate Terminal, and it shows everything.
You can make qterminal similar, once you hide the menu bar, good luck getting it back. I didn’t look at the shortcuts before closing the settings.
It’s the same as Gnome Terminal, right click in the terminal area. No need for a menu bar, you can get to the preferences without it.
And qterminal doesn’t show everything either.

That’s all I see. It records, it just shows that forever. Google won’t find a solution to that.
The Deepin Terminal might be using QT too.
Found the problem, the window is to big, apparently if the window is to big, it doesn’t show the size and time.

Deepin Terminal works now too, just make the stupid window smaller.
Resizing the window while ffmpeg is running, doesn’t make that text disappear.
