Video of panel slightly rescaling on hover

SUMMARY
At specific scaling levels (I only found 115% so far) and resolutions (1920x1080), the panel is slightly rescaled by hovering applets and letting them show the tooltips. When you hover the whole row of applets, the panel appears to vibrate. See attached video.

What the heck

I'm not immediately able to reproduce this on git-master on a screen set to 1920x1080 @ 115%. I'd like to get a few more details about your panel

- Can you attach a screenshot of the panel settings?
- Do you have any spacers in it?

Thanks

Sorry for making you wait.
I just tried and it is still happening on 6.4.5

Attaching my panel and its settings.
I am using the color picker widget somehow added into a group with the system tray - I just dragged it onto the tray.

The panel widgets are as follows:
Application launcher - Pager - Icons only task manager - Margins separator - Color picker - System tray - Digital clock - Peek at desktop
