Linear texture filtering problem with later versions

[Nightquaker]

Hello there :3
I've been noticing the problem with linear texture filtering in versions past ~0.9.1. It seems to be alot less precise in later versions.
As you can see on these comparison screenshots, interface looks alot smoother on screenshot from version 0.9.1 compared to one from 0.9.8, and that happens with almost all games.
I've used exactly same settings on both versions of emulator with texture filtering set to linear without using the texture scaling.
Forementioned screenshots:
Crisis Core FFVII
0.9.1
0.9.8
Ace Combat X: Skies of Deception
0.9.1 (notice how smooth fonts are)
0.9.8

Take Imgur image compression into account, which makes differences a little less noticeable than they really are, but you can still see them.

Is there a way to improve the linear filtering on latest version without relying on texture scaling that makes font corners very rounded?
