Bug Report: Console text becomes unreadable when using Dark Theme on Kubuntu
When running DataLab on my Kubuntu system and selecting the Dark theme, the console background becomes black — and so does the text color. This makes the console content unreadable.
I assume this might be caused by a system-level theme configuration issue on Linux (perhaps a Qt or desktop theme setting). However, in case it is not, I prefer to report it here.
Switching to the Mid-dark theme fixes the issue and everything works perfectly.
