I downloaded codeblocks on ubuntu 20.0.4, I have attached an image of the issue, the column is black with a pattern of white boxes and I don't know how to fix this.
The scaling is somewhere in the gnome settings. I don't remember how you query the dpi. You can calculate it from the xrandr output using the resolution and physical dimensions.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
