Comment 11 for bug 965323

I had a look at this, and I found the issue:
Line 369-370 (and maybe 294-295, didn't test this yet) of PanelView.cpp, the bg layer is only drawn when the dash is not opened, which seems wrong. Drawing it when the overlay is opened fixes the bug for me.

Not sure whether is has to be drawn *only* when the overlay is opened or in both cases. Not sure if this has to apply on non-GLSL only or other cards as well.
