Looks like yet another GL issue with this chipset.

Assigning to Jay. Jay: if the quality of this chipset/driver is not sufficient for an LTS, I recommend to exclude it from the list of supported chipsets and enable 2d by default instead.

Please don't kill Unity3D support for netbook users. It works perfectly other than this (low severity) bug.

@Daniel, this is by no mean a low severity bug if we are to present Unity (3d) on netbooks. It looks ugly and going for unity-2d is a far superior choice if we don't get a fix for this bug.

Last time I saw this bug it did look very minor and fixable. It's only the panel and only while the dash is open...

The screenshot in the first comment does not look minor at all. Dash is the place to launcher apps, music, video and other files hence the most widely used part of Unity. Not to mention HUD which look bad with this bug as well. Since unity's emphasis is on design and beauty this bug is not minor for a desktop interface.

Same bug here on my MSI Wind U100 netbook. I'm experiencing this bug only in Unity 5.8, 5.6 was fine.

Activate the "Blur windows" in compiz, shutdown and open again your computer... that's all

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.

I tested further and I confirm that lines 294-295 need to be patched too, otherwise the bug is present until DrawContent is called.

I still think its a higher priority bug, Unity experience looks completely broken for quite a large number of users with this bug.

Release team wise this seems fine to me, assuming that this was regression tested properly.
