Hi Kevin,

With the new Version 0.6.133 of the OpenChrome driver (from git repository) I see color steps in images. This is not related to resume/standby because it is also there after a complete reboot of the computer.

I tested that in more detail with that web-page (using Firefox):

http://www.lagom.nl/lcd-test/gradient.php

With the original OpenChrome driver of lubuntu 14.04 the gradient is completely smooth. With Version 0.6.133 I clearly see two rows of 64 bands each.

This page http://www.lagom.nl/lcd-test/display_settings.php says I would have a color depth of 24 bit. I get the same result (24 bit) with: xwininfo -root | grep Depth

My system: Fujitsu Siemens Amilo Li 1705 VIA VN896 chipset lubuntu 14.04 (upgraded to 14.04.5, but I didn't use a point release, so it is not a HWE version) OpenChrome V0.6.133

Best regards, Marty
