Visual Glitch When Changing Volume

When I am playing audio and change the volume, the volume indicator, which pops up, has a glitch where is jumps around. The volume changes fine, but the indicator sometimes doesn't move or moves too far. There are also times when the bars which indicate volume level do not show up fully, only displaying half a bar. While not a big issue, it is annoying so I would like to fix it.

I have the latest OS and restart my computer frequently.
