Strange "Filter in groups" behaviour (comparing to 1.7.3)

[IPv6]

The behaviour of some filters (or some specific combinations...) inside group has changed, comparing to 1.7.3. See screenshots from 1.7.3 and beta and attached file.
This happens only when metal computing is enabled(!)

In the file you can see MediaBlur filter with some overlay layer on it inside group.
- When MedianBlur filter has no masked pixels - everything works ok, in the same way as before.
- BUT if you add a mask into filter - 1.8.0.163 will treat "enabled" parts of filter as it should and "disabled" parts of filter... will do something wrong
Looks like disabled parts make "overlay" layer above to be treated as normal, without overlay blending mode.

Hi @IPv6

Thanks for spotting this. I logged it with our developer.
