This does not happen if I approach the VD, i.e. moving the cursor, from the desktop or over Kickeroff first, but only when the cursor moved over another VD in the pager before. Can reproduce that issue with a horizontal panel at 200% scale. Can't reproduce at 225% scale. I see this issue at 1:1 (no scaling). It's not especially reliable. I do seem to only see it when moving the cursor from an adjacent VD, but it only starts happening ~20% of the time. Once it starts happening, it will continue as long as you move the cursor quickly enough that the preview doesn't get reset. Extremely visually annoying and probably an epilepsy risk for some users. Seems to flicker at exactly the monitor rate (every other frame at 60 fps).

Created attachment 167344 [details] Screen recording STEPS TO REPRODUCE 1. At least 2 VDs, pager in the panel, a few windows opened on of the VDs 2. Move the cursor quickly from an adjacent VD in the pager to the VD with the windows OBSERVED RESULT The popup flickers, changing its size between normal and tiny (1). Sometimes other graphical glitches appear (2). Please see the screen recording: (1) the first 8 seconds, (2) the rest of the recording.
