OK so the guest additions are installed. Lets go to the next step. Run the following in the guests terminal and post the results here:
Also post a new guest log file ( as an attachment )

OK so now the guest looks like it should and seems to be happy. There is an indication that you may have an issue with the host drivers ( CRServer: context sharing not implemented ) and
( 00:00:26.772784 OpenGL Warning: CRserver: NULL context in MakeCurrent 0 ) so let's focus on that for a bit. Shut down the guest and the VBox main manager as it will not be needed. Then show me the device manager of the host so I can see what the GPU drivers list has to say.

This too looks right. So now to the problem. What exactly does not work on the guest? Please be specific and if you need to post screen shot of the issue.

When I disable 3D Acceleration on VM, I get software rendering and every graphical action takes too long. When I enable 3D Acceleration some windows and menus appear black.

What is the exact version of Mint you are using for the guest? I will try to see what qt creator looks like from here.

It is Linux Mint 18.1 Serena for both host and guest. Both are updated.
Qt Creator is also latest version.
Thank you

OK give me a bit to make the adjustments ( stop what I am doing ) and I will check to see if there is an issue that you and I can resolve. If not then it should be posted at
bugtracker. Shouldn't take more than an hour.

Alright I have confirmed that qt creator does in fact have issues with 3D acceleration in VBox. Some users have found they could set LIBGL_ALWAYS_SOFTWARE=1 before launching QtCreator allows them to work, but this needs to be addressed with the DEVs. If they can or can not fix it they would be the ones that could tell. Sadly they are really busy and this may not be what you wanted to hear but that's the best I have.
