On Mint 22 and Archlinux Codeblock is unusable, as you can see on the attached picture we can't see the wxsmith icons.
I saw no such issue at work with Windows 11. I haven't tried on my Mac Studio yet so I don't know if the issue also exists on the mac.
Taking the bottom window doesn't help. Is it possible to undock that area so I can see the Icons?
