I've seen this issue since switching to wayland back before the Mega Release, I mentioned it on IRC but wasn't sure if it was a bug in kwin, the graphics drivers or a hardware issue I'm certain it's not monitor burn in - it changes too much and it often flickers I'm currently running Qt 6.7.1 KF from Git, and Plasma from Git, I've seen this going all the way back from before MR6 and Qt 6.6 The ghosting remains even after Chromium is closed and it's a Wayland enabled chromium (so there's no Xwayland involved) Screenshots using Spectacle don't show the artefacts, I'm attaching a video but I'm not sure you can really see the flickering but you can see the Chromium tool bar I've also seen strange things with the kicker menu but I'm not sure if that's related or not, it's like it pauses before displaying the final frame unless you move the cursor I'll try and film that too
