Above attachment is what happens on MATE (note the icon is not only not correctly scaled, but it shows displaced/not centralized on the task bar).
This doesn't happen with Wine 9.1, so this is a regression.
Pretty much the same thing happens in Cinnamon. The icon that was centered before is now in the upper left corner of the icon boundary.
