Cura 4.4.1 install on Ubuntu opens without menu items

[Lemoncluster 0]

Hi, Another newbie question...  sorry... 

 

I have run the previous Cura version on my Ubuntu 18.04.4 system.    It has run fine for weeks but now loads and runs without any dialogue boxes being populated, that is, the menu items (all text) is blank.   The 3D frame is shown and I can rotate and zoom the box. Clicking randomly around the screen can open a dialogue box, but it is blank.          I have loaded the most recent Cura 4.4.1 which runs in exactly the same way...        The Ubuntu system is regularly updated, so I suspect that the problem came about in that way... I will ask for help in the Ubuntu forum, if i can get an understanding of what is missing.... anyone help?  

 

Regards,  Dave.

I tried a (another) new install.  This time not on my desktop, but in a directory for executables within my home dir.   

There's an improvement!         It opens and runs as normal, but has the top right-hand part of the window blank.  If I click in the blank portion, i can roll down the menu there and even drag it to a different part of the screen.  It will slice and save..    Really odd...  ??
