Would you mind to try running it with reporting set to the highest level
to see what the driver reports ?

Another idea: Did you try running it with a higher contrast value ?
IIRC among the things that changed between 0.4.5 and 0.5 was an
expansion of the contrast range to [0, 1000] to make it the same as
other drivers.

Any feedback is appreciated.

Hope it helps
