RE: Building OSCAR Ubuntu 20.04
I installed the nvidia-cuda-toolkit and cuda 10.1.  Thought maybe some graphics stuff might be missing and perhaps that would change something.

Did a $ make distclean, which by the way, does not remove the subdirectories /html and /translations in /build/oscar.
Then 
$ qmake ../OSCAR-code/OSCAR_QT.pro 
$ make -j4  

-j4 speeds up things considerably!

Lo and behold OSCAR now runs!  Don't need BROKEN_GL.  Curiously, the OSCAR debug window reports
Code:
10432: Debug: Operating system: Ubuntu 20.04.1 LTS
10432: Debug: Graphics Engine: 4.6.0 NVIDIA 418.152.00
10432: Debug: Graphics Engine type: LegacyGFX

Is LegacyGFX correct?

In any case, the graphics seem to be crisper (and faster) than BROKEN_GL.  The graph traces are sharper as well.

It's saying LegacyGFX when running because that preference is sticky. Once you turn it on, it stays on until you turn it off in preferences:

Preferences > General > Desktop OpenGL

(I'm betting yours still says "Software Engine".)

sawinglogz, Yes you are correct.  Just changed it to OpenGL.  The app restarted and it's even better now.  Now running OSCAR 1.2.0-rc.2+master-1faaf625-plus (linux x86_64)

Hah, now I need to take out the sleep commands I put in for debug!  Must of added over 10 seconds of delay.

Yeah! Commented out my sleep statements. Now in OSCAR in a blink of an eye!
