      Description

      Images that are scaled and have mipmap enabled disappear after the computer was suspended to RAM and resumed. This bug was encountered on Ubuntu Linux 16.10 with a Nvidia graphics card and the driver from Nvidia (version 367.57, as recommended in the Ubuntu settings dialog). It does not happen with the integrated graphics processor from Intel on the same machine.

      Attached is an example how to reproduce the bug and screenshots before and after the suspend/resume.
