Using gnome, kde, and ubuntu desktops under wayland is giving problems with chrome and brave browsers. If I have a single window open, it's pretty good, but if I have multiple windows open (a half dozen for brave, 33 for chrome is typical for me), the screen frequently flickers and I get portions of the different windows showing up. In many ways this is similar to screen tearing (historically fixed with vsync updating in X), but it doesn't have a clean edge to it, and it's not a matter of top of the screen one image, bottom the other, instead it's a band (~1/4 of the screen high, not always in the same location, but tends to be ~1/3 down from the top more frequently) and in that band I see portions of other windows that are behind the forground window.
