XCTU 6.3.1 Linux x64 UI problem

Hi,

I’m using the latest version of XCTU for x64 Linux on my Debian OS with KDE. It works fine but the UI is weird. I can’t properly see what is written at Configuration window while configuring my Xbee nodes.
The text is written in gray color on a white or even gray (darker) background and it’s really hard to read it.

Here is a screenshot

Is this running from xterm or the console?

What version of Debian?

You might want to try running it from various X sessions/emulators to see if the display changes.
