If you use Ctrl+Esc to clear the execution history, the window turns black.
I tested os linuxmint 20, 21 and ubuntu 22.04.
I tested pc Asus d509d laptop, vmware.
It is okay as long as it does not deviate from the default height of execution records.
But when you get out, it becomes a black screen.
This is not the situation that occurs on all PCs.
I don't know exactly why.
