For those wondering, I am not talking about "subtle" screen shake or shimmering due to aspect ratio or border settings. They are obvious glitches that should not be happening (stock settings, happens on the later firmware but not the earlier).
Here are some examples (I apologize for the embeds. Even when linking them properly NA is still treating them as embeds):
Kirby's Adventure HUD bounce/shake (skip to about 50 seconds in) -
Ninja Gaiden III screen bounce/shake (skip to about 10 seconds in) -
Major graphical glitches in Ninja Gaiden III's vertical section in Stage 2 (does it on both the new and old firmware). Same thing happens in similar vertical auto-scroller sections in Shatterhand -
