When certains texures are enchanted in REI GUI and faster GUI has screen enabled they break.
This seem to affect all CIT items from my resource pack and some vanilla potions for some reason.
The affected potion is night vision.
My vanilla trident with no texture change is affected.
My golden helmet with changed texture in vanilla is affected.
My elytras with CIT are affected.
Some thing weird is that if my mouse cursor is on the item just before a broken item, they don't break.
i have caching entry rendering off in REI.

on this pic it's my inventory with enabled screen

Here is the don't break situation

When enabled screen is off

I mean if you can recreate such issues without FasterGUI, report it to REI. Might help with the future compatebility. I think the black enchant glow only started after I had to forcefully change some parts of the render logic to get the buttons of REI to work. So if the buttons would be rendered correctly, I could remove these workarounds to get everything(hopefully) working.

ok thanks i'll try to report issues i had that were related to weird menu rendering

Known issue. I tried to fix the enchant glow as much as I could, but REI does a lot of weird crap. It's always the first glowing item in a row of glowing items that will be just black. Without botchy workaround it's all glowing items.

If it's always the 1st of a glowing row why is my helmet not broken in the top right, why is my trident broken since there is an enchanted shield before and why doesn't i have the problem with books ?
It's really weird
I hope you'll be able to find where the problem exactly is since your mod is really promising but this bug is annoying.

To clarify, it's not an issue with my mod, it's just my mod trying to patch together REI that uses incorrect blend modes and render logic.

This is how the mess looks like REI renders internally without FasterGUI. Notice the missing buttons at the top right/bottom, due to them being fully transparent(REI just deletes the alpha values there cause?!?) So for now I'll focus on more important things than a few blacked out items, since it is useable now(certainly more usable than without the hacky fixes).

This as already been issued to REI ?
Because it seems to be a really big problem.

No I haven't created an issue yet, since this is not visible usually (due to there being no alpha on the monitor), and this still being an experimental mod.

no i'm talking about REI system being broken, i imagine that this is the cause of every visual weirdness i encountered in the past with like an element that should be behind that's in front, weird transparency etc

Removed screen buffering from the mod.
