Problem with Leica Monochrom DNG files and Serif raw engine

Recommended Posts


as of build 118, DNG files from Leica Monochrome MM (first version) appear black when they open with the Serif Raw engine (with the Apple engine they appear fine). I have to drag the exposure slider all the way to the right to see a faint image. Before build 118, the raw conversion was excellent. I've installed build 223, but the problem persists.

OK, this happens only when Metal acceleration is enabled.



With Metal acceleration deselected, the file loads fine. Is this normal?

Hi Thomas_M,
Thanks for the additional info. It works fine here with Metal enabled. It's probaby something specific to to your config/graphic card. We are looking into this. Just to rule this out, do you mind resetting the app and try again: press CTRL while launching the app until a Clear User Data appears, keep the first three checkboxes ticked then press Clear. Reload the RAW using the Serif engine - does it still display black? Are you using a scaled resolution or the native screen resolution?

I reset the app and tried again, reloaded the RAW using the Serif engine and it displayed black. I'm using the native screen resolution (Default for display), not a scaled one.

As I wrote before, the problem started with build 118; before that, it worked fine with my configuration.
