Some kind of issue with filtering. (A delay?)

[Ryudo]

While I was playing Harvest Moon, and also Star Ocean Second Evolution, I noticed there's something buggy going on with the filtering of graphics now.

Whenever a character stands still it's perfectly fine, but when a character starts moving, the sprite becomes pixelated and it stays that way for about 2 seconds before being filtered correctly again by PPSSPP.

Here is a screenshot of it working as it should:




And this is where the bug occurs:



I am 100% sure that this didn't occur in older versions. Unfortunately I don't have access to the older versions anymore where it was working as intended... but could this possibly be looked into?
