Flashing and blinking bug in Oracle Universal Installer Database 11gR2

The latest release of Oracle Database came with an overhaul of the Oracle Universal Installer GUI.  There is a strange interaction between gnome and the OUI (runInstaller) that causes the screen to flash uncontrollably and not resize properly when the screen resolution is 800×600 and gnome is configured as per defaults of RedHat Enterprise Linux and Oracle Enterprise Linux, which consumes a few pixels on top and bottom reducing overall screen space to under 600 pixels tall.

This video was produced while sitting on a flight from YVR (Vancouver) to YOW (Ottawa), in seat 1A in J (Exec/First) class.  I had food over my MacBook Pro, and it’s a wonder the built-in microphone picked up anything.  I demonstrate this via a VNC connection in response to a question posted on Oracle forums regarding using VNC to install.  It is not VNC that is at fault; it is the lack of screen realestate that causes Oracle to blink and flash, and ultimately fail to visibly draw the “Next” button (although the ALT-N key combo still works)

Note that Oracle specifies a minimum of 1024×768 resolution for 11gR2 installation.  See documentation here.

    Eric, this annoying problem makes entering on the OUI extremely difficult. I find a workaround resolution to this. If you pick the lowest screen resolution say 640×480 and used screen depth color of thousands color rather than million. The flashing stops running the OUI in full screen mode (Host key (ctrl key) + F). This is very handy. I think this problem only occurs for 32 bits machine. I will report this back to My Oracle Support contact. Thank you for your help site.
