trouble for compiling on linux

[FRADSOL]

Hello
Since I switched from windows 10 to linux I'm dealing with a new trouble which is when I'm compiling the output window is awfully small I barely can read it. Have you got any idea? thanks in advance!!

Some wired DPI settings you have here...
Are you using some high DPI 4k screen?
To get a proper support of High DPI in codeblocks (scaling the toolbar for example) you need the latest version from trunk or a nightly build. You can find a repo in the nightly build forum.
For your output window problem maybe you can find here some help: https://wiki.archlinux.org/index.php/HiDPI

You probably need to switch to another terminal app. Settings -> Environment -> General -> Terminal
