I am running Emacs inside a virtual machine, and are experiencing redrawing problems when scrolling or adding/removing lines of text. It seems only a small portion of the window is being redrawn, causing some lines to be repeated and others to be obscured.

I have not experienced any similar problems with other applications inside the virtual machine.

The problem is present whether I run the virtual machine in fullscreen or windowed mode.

This is my setup:

  • Windows 7 Pro 64-bit host OS
    • nVidia GTX 770 graphics card with latest drivers
    • VirtualBox 4.3.6
  • Ubuntu 13.10 64-bit guest OS
    • VirtualBox Guest Additions installed
    • 3D acceleration enabled
    • Cinnamon 2.0.14 desktop environment
    • Emacs 24.3.1

My workaround for now is to run Emacs in terminal mode, but I would prefer a solution that makes it work properly in its own graphical window.

I have had the same problem and it seems that disabling 3D acceleration in VirtualBox properties solved the problem.

Thank you for the answer. I have since gone over to using GNOME Flashback desktop on this VM, and don't experience that problem there, even with 3D acceleration enabled. I will add that as a separate answer, but mark yours as the accepted one. – Lars Haugseth Apr 28 '14 at 18:29

As a workaround in cases where Cinnamon is not a requirement, I have found that when using the GNOME Flashback desktop that ships with Ubuntu 13.10, I do not experience this problem, even with 3D acceleration enabled. The functionality and feel of GNOME Flashback is pretty similar to Cinnamon, at least for my use.
