Krita 5.1.0-beta2 (git 973c92a) SUMMARY Something I've noticed for a while: when using the Halftone filter, selecting the Alpha mode defaults the generator to None, which seems to have no practical purpose from what I can tell, as it appears to do nothing at all, even when configuring the postprocessing options. STEPS TO REPRODUCE 1. Utilize the Halftone filter through a filter, filter mask, or filter layer. 2. Select Alpha mode. OBSERVED RESULT The default generator is None, which seems to do nothing. EXPECTED RESULT The default generator should probably be Screentone like the other modes. Also, if there is no practical purpose to the None mode, it should probably be removed.

I guess the screentone generator should be used as a default for the alpha mode. The "none" option is useful in the case when there are multiple channels (rgb, crmyk, etc.). That allows you to not apply the filter to some channels.
