Hello,  
I’ve downloaded 3slicer on ubuntu and I have this strange problem where UI is pixelated as shown on the attached image:

I’ve tried different versions of the program and the problem still occurs.

Probably your sysytem settings for Qt application scaling need some tuning. See for example [here](https://techienotes.blog/2019/01/21/fix-qt-apps-scaling-issue-on-hidpi-screens-on-ubuntu/) specifications [here](https://doc.qt.io/qt-5/highdpi.html#high-dpi-support-in-qt).
