Random black background on watermark

Description of the issue
Hi,

I've been having a seemingly random issue with the watermark. When uploading images - one at a time or in bulk - some images have a black background on the watermark (with appropriate opacity) and some are normal. For example as in this screenshot: https://www.dropbox.com/s/ez6el13zd6482ut/2017-11-25_17-52-11.png?dl=0

I have tried
- Scaling down the watermark
- PNG 8 / PNG 24
- Changing Opacity, Margin, and Size settings of the watermark

Yet cannot reliably change the behavior - it seems always random, even if I upload the exact same images 5 times as a test, some will be normal and some will have a black background.

Attach the watermark file

I have tried all these with identical results

I used your watermark and I got the same bad result. The default watermark file doesn't show that issue so the problem is your watermark file.

Try to re-generate your watermark and try to use a smaller image because that eats ram.

I have explained the settings I used in Photoshop to create the various versions. I've recreated it over 7 times with unique settings as I mentioned. I've never had issues with PNG transparency before. If chevereto requires specific settings for PNGs in order to properly process the transparency, can you please provide them here?

Otherwise, please provide what settings you used to create your version which works?

To be honest, I don't know why your watermark causes issues and default doesn't. Maybe is just the size of it, try with a smaller watermark.

If still fails I can generate the watermark for you.
