I have the same problem, which started on 7.0.0.38 with Ubuntu 26.04. a RX 9060 XT and a Samsung TV connected in HDMI as monitor, 4k @ 60Hz. The horizontal "bar" so quickly disappears that it's barely visible. It covers like 50%-70% of the screen width, is usually located near the bottom of the screen, and has a height of 10% of the screen height. It's as if a "cloud" of random pixel was appearing in that zone, for a very, very short time. That happens about once or twice per hour, roughly.
