Bug Report

Installing Ears mod alongside Angelica & The Betweenlands results in rapid screen flickering graphical issues.
Issue only occurs when the players empty hand is rendered on screen. Likely an issue with the 1.8+ skin format.
Issue does not occur in third person. Nor if any of the three mods are removed.
Betweenlands does some weird shader stuff, notably with fireflies/wisps, so there's likely conflicts there.

Final Checklist

• I have searched the issues and haven't found a similar issue.
• I have read the known incompatibilities and this is not related to one of those.
• I am running an officially released version. (Or, if I've compiled it myself I plan to fix the issue)

Have you tried disabling hudcaching? What about temporarily disabling the GL State Manager/Cache?

[Lylythii]

Setting enableHudCaching to false prevents the flickering. Though now the game screen appears entirely black (excluding the hotbar), unless holding an item.
Not sure where I should be changing GL State Manager/Cache.

[mitchej123]

There's an option to disable it under Advanced I believe. It doesn't persist across sessions, but it's useful for narrowing down issues.

[Lylythii]

Ah! Found it under the Performance category. Toggling it off does in fact prevent the flickering issue.
(As does changing graphics from Fancy to Fast. Though that's not ideal.)
Hope that'll help to narrow down the issue.

[mitchej123]

That will help narrow it down. Not sure I have time to dig into it currently. One last question - is this with or without shaders? I'd suggest try disabling iris in the angelica-modules.cfg, and see if it still breaks.

[Lylythii]

I did not have any shaderpacks enabled. Disabling Iris did not resolve the issue either.
Take your time! This isn't urgent. I'll disable Ears for the time being.

Have you checked what happens with HUDCaching enabled but the GL State Manager disabled?

[Lylythii]

If I'm not mistaken:

• Hud Caching enabled + GL State Cache enabled -> Flickering issues when empty hand is visible.
• Hud Caching disabled + GL State Cache disabled -> No flickering issues, nor black screen.
• Hud Caching enabled + GL State Cache disabled -> No flickering issues, nor black screen.
• Hud Caching disabled + GL State Cache enabled ->No flickering, black screen when empty hand is visible.
