Blender Version

Worked: (optional)

Short description of error
After seemingly a random time, the interface shows just gray balls where there used to be icons for camera, ortographic view and the rotation gizmo. When this happens, it is also imopssible to pick anything in the viewport. The outliner still works and meshes gets highlighted in the viewport when picking in the outliner. But the viewport itself is not responding. This happens every single Blender session started, but sometimes after five minutes, sometimes after thirty. The one time I saw when it happened, it was when I hit the button to create a new texture.

Exact steps for others to reproduce the error
I cannot reproduce the error with a certain command, it seems to happen at random after some use. Maybe when memory starts to become full?

@Anders Magnusson (hyperkub): Since this is not reproducable for others, can you check your memory when this happens and report back? And can you also check if your computer meets the minimum requirements https://www.blender.org/download/requirements/ ?

I had this happen a lot too on 2.80 and 2.81 on a 2016 Macbook pro with intel integrated graphics. Occurrence was very random, I couldn't identify any specific action that would lead to it although it seemed to occur more often in more complex scenes. Personally I haven't seen it happen anymore in recent 2.82 betas on mac, but I also switched MacBooks in the meantime and now have one with a discrete GPU.

@Anders Magnusson (hyperkub) Please check if the issue still exists in the current buildbot builds. If yes, provide a screenshot.

I have now run the latest build of Blender and have not yet experienced this issue. It seems to be fixed!
