Screen acts strangely when clicking Dash icon

[Claes Trygger]

I'm new to Ubuntu One so I don't really know what info to submit, but my problem is as follows:

Everything seems to work just fine in 16.04 - except for one thing: Dash. When I click the icon (or press the superkey) the screen goes sort of crazy: coloured strips and odd stuff appear. Sometimes the computer freezes and I have to start all over again; sometimes it is possible to save the day by (fairly quickly)clicking the Dash icon once again - and sometimes things work out by themselves. I have searched for a solution on the internet, but in vain. Maybe it has something to do with memory mapping?

Computer info: AMD Athlon 64 Processor 3500+ with 3 GB RAM (I think it was originally 1 GB but I extended it some years ago) in HP Pavilion 3510no desktop (old stuff; probably at least 10 years old). Graphics Gallium 0.4 on NV 46 (according to Settings - what do I know ...)
