Since early February I have not been able to run FreeCAD due to some sort of problem with MESA/Radion graphics (the details of which are beyond me).
Today, after the 20180226 upgrade, I can now no longer run the EAgle PCB design software!
To be more accurate, I think it is running in a window, it is just that I can't see it. Its just black...

Any tips to get me running again?
