No flickering, but it "tears up" when moving, it gets a "ghost" following it sort of closely https://youtu.be/E31wCNpdaOs
This is nature of de-interlacing. When object is moving in interlace video, 2 fields are different, so eventually you see the ghosting.
Weaving de-interlace using in Scaler is targeted to static objects which is majority of time. It gives native resolution as sum of 2 fields.
Another "cheap" de-interlacing is BOB which has half resolution with twice higher frame rate. It has bad result for computer graphics with hard color transitions, so it produces a lot of flickering on static objects. So it's definitely not suitable for Minimig. Workbench will be full of flickering lines.
Modern TVs use very sophisticated algos like motion adaptive and others which is not available (it's resource and computing expensive) for MiSTer.
