I run Konsole with zsh on KDE on Arch as my main terminal interface. I have a custom color sheme. But, something happened, and the colors stopped displaying right.

How it works on my machine:

When I launch Konsole, the screen background color is grey (and should be blue). When I resize the window of Konsole it gets updated to the right color. When I write a command and press Enter, a new line is converted to the right color. The grey color is also updated by a little rectangle that pops up in the middle of any window when I open it (so it leaves a blue rectangle on a grey background). It is also updated by autocompletion (like pressing ls and then Tab).

Things that might have started this:

an update
installation on MPJ (for Java school things)
installation of jupyter via pip
This is what it looks like:
