Comment 4 for bug 968680

This is due to the offset for the progress bar fill not working as intended. The current way it is being done, it does not scale at all when the icon size is being changed. While debugging this, I also noticed very large icons, ie, size 54, also is incorrect in that the progress bar fill starts too far to the left.

I have figured out what the scaling ratio is (0.125) and will being proposing a merge soon.
