DrRacket (both 6.8 and 6.9) when installed has issues with GUI. Racket developers suggest that the problem could be in the os side. I have attached the screen shot. The same kind of problem is for other windows in Racket IDE.

I tried changing the file GTK_CSD=1 in the file /etc/profile.d/gtk-csd.sh to GTK_CSD="" but it did not work.

I don't know why did you used an sh package and not the PPA available who can work with the package manager you have

Just use apt

DrRacket PPA



sudo add-apt-repository ppa:plt/racket

sudo apt install racket
