Description
Virtual machine is constantly flickering and when I log in grey base coloured squares appear until I press in the higher left corner where dash is. But flickering is making working with VM impossible.
I am using Virtualbox 4.3.26. My host is Ubuntu 15.04 with custom NVIDIA driver (version 346.72) for Geforce GTX 960M. My guest is Ubuntu 14.04.02 LTS.
All details about this annoying regression are described and available here: https://forums.virtualbox.org/viewtopic.php?f=3&t=67823

Replying to frank:
You say it's a regression: So you don't see this problem with an older version of VBox, is that true? Which version is that?
Sorry for my English... I obviously do not understand what regression means. This annoying bug exists at least from 4.3.26. It goes on in 4.3.28.
Also, I assume that disabling 3D in the VM settings works around this problem, is that true?
Will check this when I can later.

And is this a duplicate of #13653?
No, I don't think so. Since flickering is not conditioned/caused by pointing mouse to a window. I would imagine it has to do something with cursor blinking. For example, if I run a script in terminal each line that is printed out causes flicker. The same is when I am typing here. Almost with every stroke on the keyboard it flickers...
A side note: I am so very sorry I wasted 2000 EUR for purchasing a gaming laptop (hoping to get fast, top notch laptop) with NVIDIA graphics. I will never ever buy a computer with NVIDIA graphics. This wasted at least two full weeks of my life and destroys my vision... Not to mention what havoc NVIDIA is causing to my host system (not being able to log in, black screen, ...) I needed to say this...

No. It makes it even worse. I disabled 3D in VM settings and now flickering is much much worse.
