Final Fantasy 8 (VIII) strange graphical bug during battles

[Metzli-Cilalti]

Updated cores on my Anbernic device (RG353M) and the new pcsx rearmed_rumble core started acting weird: if I use Enhanced resolution, the HUD completely breaks (also noticing a very weird. coloured swirling effect when the battles start and the screen fades like it usually does, which wasn't present at first). The names of the characters, health values, ATB bars and the text on top all blink repeatedly. This continues until I disable enhanced resolution. The very strange part about this is if I then go back to using the enhanced resolution: the blinking does NOT reappear, that is until the next battle. So basically for each battle you have to go disable enhanced resolution and then re-enable it to make the text not blink.

I've fixed the flickering.

I don't think the battle transitions ever worked correctly with enhanced resolution. I haven't looked in detail, but it probably relies on some edge cases like 1 pixel triangles which behave very different at double resolution where they become 2 pixel wide. Something to investigate some other day.
