Summoner Names and HP Bar blurry when moving (Summoner's Rift only)

I posted this on help and support, thinking 'tech support'. My bad. Anyway...

So on Summoner's Rift (but not Howling abyss) the white summoner names above the champion, as well as the HP bar, are blurred slightly when moving. It's more noticeable with faster move speed (for example, the boost you get when leaving the base).

This is a very minor graphics glitch that doesn't affect my actual game play at all. It makes my eyes wonky though - especially when playing a high-movement-speed Janna build...

anywhoo...

Again,** this doesn't happen on Howling abyss**. I've read (and tried) a few various fixes and graphics settings changes, but almost all of those were for people experiencing very blurred HUDs, etc.

Any suggestions? ...Or is it a feature (ala Motion Blur because you're moving so fast? ??? LOL)

Thanks in advance. :D
