masks and histogram not displaying properly

[ceg]

I use a lot of stacks to combat noise in hand-held night photography, or simulate long exposures. I have noticed that the thumbnail in the layers panel is pretty dark, and any masks are a darkish gray (maybe black) as well. Inverting them etc. has no effect on the thumbnail. Neither has modifying them with a brush.

Furthermore, the histogram does not reflect any adjustments made to the image. Once the image is saved, closed, and reloaded both layer mask thumbnails and histograms display properly.

Hey ceg,

I've seen a few adjustments that display the second part of what you described but my layers don't seem dark. Can you attach a document so I can see what you're seeing? Also, a before and after screenshot would be super! Just so I've got it to attach to a bug report.

Thanks Chris, sorry for the late reply, but working from home kept me busier than normal. There is no "before" screenshot only once a few adjustment layers are added.

As far as the histogram goes: it seems to take a while to update. For a 20 image stack an exposure adjustment updates the histogram within a second or two. I was too impatient to wait for the histogram to update after a curve adjustment. It seems to take "forever" (> 10 seconds :-).

Slow processing seems to be the cause of the black masks as well. Now, a few minutes later, they all turned white as expected.

I am using an i7 2.6 GHz processor with 32Gb of RAM.

As an aside: I was never a big fan of these little mask icons: they never seem quite to show what's going on.

speaking of the mask icon being a bit off:

the black and white adjustment was only masked for the foreground rock at the lower left, though the mask icon shows a big black blob in the middle of the image. Maybe I don't understand those mask icons, but it seems counter intuitive.

Hi ceg,
Welcome to Affinity Forums
Regarding the mask icons - they only display the area you have painted on the mask (as opposed to the whole document area as in Photoshop).

Thanks MEB

not sure whether that's all that useful to see all these masks at varying scales throughout the document. Even though it's a small quibble, I'd prefer them on a consistent scale.
