Progress on linear texture filtering

[Nightquaker]

Hello there :3
It's well known that linear method of texture filtering affects 2D elements in games in not a good way, causing them to glitch out. And sometimes that issue is quite bothersome in games like Canabalt and Star Ocean series. Is there any progress on resolving that problem?
Also, might be a little bit off-topic, but I heard that newest revisions of emulator have improved texture scaling so it doesn't have caching issues, is that true?
Thanks :3

P.S. You can see texture filtering glitching out the text box and Yukari's face on a screenshot.
