I have an app I've developed in Qt 5.3.1 that doesn't display data in output text boxes when using the Linux Cinnamon desktop in VirtualBox with 3D acceleration enabled in the display settings for the virtual machine.

It does this when using the Cinnamon desktop in any Linux Distro (I've tried Cinnamon with Linux Mint, Ubuntu and Debian). The regular Unity desktop in Ubuntu and the Xfce desktops in both Linux Mint and Debian have no problem. Just Cinnamon.

I don't know if this is a Cinnamon, VirtualBox or Qt problem. Months ago I registered a bug with the Cinnamon folks but I never saw a fix, or that the problem was replicated anywhere. If I disable 3D acceleration for any of the Cinnamon virtual machines in VirtualBox the problem doesn't happen.

I'm posting here because maybe some Qt developers have seen similar problems with Cinnamon in either VirtualBox, or a native Linux machine.

Any comments or replies would be welcome. Thanks in advance for any.
