Topic: Blurry 2D acceleration

I recently did an apt-upgrade which seemed to install new kernel etc, and now when 2D acceleration is turned on my screen is blurry.  Not only does it look blurry, but capturing a screenshot captures a blurry image!

I am using a screen driven from the HDMI port, and do not have and eDP screen installed.

In /usr/share/X11/xorg.conf.d/60-novena.conf under the Device section if I set the UseGPU to true:

Section "Device"
        Identifier "novena"
        Driver "armada"
        Option "UseGPU" "true" # change to "false" to disable 2D acceleration
        Option "XvPreferOverlay" "FALSE" # FALSE enables xv acceleration

        # The next two options switch it from galcore to etnadrm mode
        Option "Screen"        "0"
        Option "AccelModule"   "etnadrm_gpu"
EndSection

Section "Files"
        ModulePath "/usr/lib/xorg/modules/"
        ModulePath "/usr/lib/arm-linux-gnueabihf/xorg/modules/"
EndSection

My screen looks like this:

And with 2D turned off:

Section "Device"
        Identifier "novena"
        Driver "armada"
        Option "UseGPU" "false" # change to "false" to disable 2D acceleration

My screen looks fine:

Here are the novena-eeprom contents:

Current EEPROM settings:
        Signature:        Novena

        Serial:           262

        LVDS channel 2:

                Flags: 0x41 (channel_present,ignore_settings)

And the result of cat /proc/version

Linux version 3.19.0-00485-gc5f2138 (xobs@xobs-novena-laptop) (gcc version 4.9.2 (Debian 4.9.2-10) ) #858 SMP PREEMPT Tue Sep 15 13:41:23 SGT 2015

And oddly, when I run Novena EEprom GUI it the window contents are initially blurry, but when I select a different tab the contents of that window are not blurry, although the rest of the screen remains blurry.  When I tried to make a screenshot of that screen the whole capture was blurry.

Any suggestion would be appreciated.

Re: Blurry 2D acceleration

That is very very interesting.  I'll let jnettlet know, because it seems like there's definitely something wrong with how 2D acceleration is acting.
