SUMMARY When I drag a maximised windows so that that window can be a smaller size, a large ghost-like big image of the window flickers on the other monitor. This is especially apparent when the wobbliness is big. This is not a serious problem, but hey, people use wobbliness to look good, not for practical reasons. So, looking good is all that matters, and this makes it look less good. STEPS TO REPRODUCE 1. Increase wobbliness 2. Maximise a window 3. Drag down the title bar of that window OBSERVED RESULT On the other monitor, a large ghost of the window flickers. EXPECTED RESULT I do not think the effect should be shown beyond the current monitor, when resizing a maximised window. Maybe it is better to confine the animation within the monitor, not expanding it to the other monitor.

Huh, apparently, I didn't fix this bug completely.
If you disable the Maximize effect, can you reproduce this bug?
Also, please post output of qdbus org.kde.KWin /KWin supportInformation
I can't reproduce it (on both Wayland and X11).
Given the expected result, I'm not sure what you mean by "a large ghost-like big image of the window flickers on the other monitor". Does the visual artifact look like https://bugsfiles.kde.org/attachment.cgi?id=101552?
Created attachment 116643 [details] When it happened. I had tested Wobbly in a slightly older KDE last week, and the visual artefact was a lot worse (the artefact did not even disappear after the animation). This time, it was not that bad, just a minor annoyance. The "Maximise" seems to have been enabled by default. When I turned it off, it no longer happened. Maybe you could add a warning about this in the description, like "Not to be used along with the Maximise effect"? I had captured the "weird animation" before seeing the comment about "Maximise effect", so I will attach it. You can see a large version of the window flashes at the right corner of the left monitor. I forgot the Wobbly parameters, but with certain parameters, the flashing large window was a lot bigger. Anyways, I think you can close this issue, as this can be solved by simply disabling "Maximise". Thank you for your help. I am not sure if I could say this here but if you do not mind, there are really minor two additional things... (1) While wobbling, I can see some sort of seam between the title bar and the client area, as if the title bar and the client are not one piece. (2) Maybe apply anti-aliasing to the wobbling edges? It looks a little bit jaggy.

Prior to 5.14.1, the Maximize and the Wobbly Windows effect didn't go along quite well. > I had captured the "weird animation" before seeing the comment about > "Maximise effect", so I will attach it.
