I find a lot of mods unfortunately don't respect/adhere to the setting screen safe area. I could list a few mods such as detail armor bar, boathud, and customHud. But I don't know if you can fix this issue for each mod. But this is the only mod that seems to add the screen safe area feature so I come here to report the "bug".

Does Bedrockify compensate for AppleSkin, or vice versa? It looks like most mods don't recognize the safe area and mod developers generally refuse to support Bedrockify.

AppleSkin has worked fine for me.

Yeah, that's the reason I specifically asked for AppleSkin as it didn't support this in previous versions (and previous MC versions). Currently it does. Is this fixed on AppleSkin's side or Bedrockify's side?

Is this fixed on AppleSkin's side or Bedrockify's side?

It is fixed on bedrockify side. Compatiblity of screen safe area with other mods is usually implemented in bedrockIfy explicitly.

Apple skin compatibility seems to still be a bit broken as of writing this (v1.9.6 for mc 1.21). The overlay it adds appears to be twice the specified size of the safe area.

(safe area set to 10 and 1 accordingly)

@mineland-2048 I've fixed AppleSkin compatiblity again in 03b1890, now works properly with safe area and hud opacity. It will be published in some days! Thanks for letting me know!
