Rockbox dev: 2048 - low contrast and misaligned screen contents??

[LennoxConner]

Hi,

Today I built rockbox dev from source.
Installation works fine.

Unfortunately the game "2-48" is barely playable on
the Clip Zip since Speed Test essay writer the contrast of the "chess board" is very low
and "something" (cannot recognize for sure what it is) is
overwriting the boards from the left side of the screen.

Is there a way to fix it beside removing/changing the code itsself?

Best regards,
