Counters and progress bars on the launcher are blurred if the launcher icon size is set to an odd number of pixels

Using Ubuntu 12.04
Unity version: 5.10.0-0ubuntu6

Many apologies if this is in the wrong place.

Steps to reproduce this bug:
Change the size of icons in the Unity launcher through the appearance settings. If the size is set to an ODD number of pixels then the counters and progress bars that are used by some applications in the launcher are blurred. When the size is set to an EVEN number then there is no problem.

See attached screenshots

Obviously its not really much of an issue as what's one pixel between friends, you can just pick an even value, but perhaps it would look better to just restrict the values to even numbers? Or perhaps its just my system, if so sorry for wasting anyones time. I'll include some screenshots for reference.
