According to FrescoLogic/FL2000#42 there is no option to configure FL2000 to linear sRGB input. By default, Linux gives linear RGB buffers to DRI, this must be changed somehow.

Implemented workaround with forced compression XRGB8888 -> RGB565, this solve the issue and also helps reducing USB traffic.
