Hi EmT, I tried to reproduce that “error” by changing the zoom factor (was assumed by DM1 to be the root cause). But this had no impact on the filters, all worked as normal. So I tried changing some other parameters. And finally I found out that it is the alpha lock that’s causing this behavior. If you protect the transparency in the pixel layer then the live filter will not work, if in preview mode. If you change into list mode by clicking the hamburger, then the live filter does work!
Please let me know if you can reproduce this behavior on your Ipad as well or shall I provide a screen recording?
