Textures not rendering properly or on Android with GLES2 and ETC1 VRAM compression

[CenTdemeern1]

I don't know of any potential duplicates.

Godot version:
3.2.1.stable (official)

OS/device including version:
(Mostly a copy-paste from a previous issue, this time with GLES2)
Microsoft Windows NT Version 10.0.18363.900 running on an Intel Core i3 and integrated graphics,
I'm using GLES2.
My Android device is a Lenovo K6 (K33a48) running Android 7.0, with security patch level "November 1st 2017", build number K33_S231_171114_ROW, with an 8-core MSM8937 processor clocked at 1.4GHz. Has 2 Gigs of RAM and 16 GB of internal storage.

Issue description:
I have 2 textures.
One is a blue sphere collectible thingy, and one is a grid placeholder texture.
That grid placeholder texture works kind-of-fine, while it definitely has issues.
At least it's visible.
Then, here comes the kicker, That blue sphere thingy isn't even visible!
Not in-game, and not on the hud!

This screenshot was taken on Android, where it looks wrong:

This screenshot was taken on PC, where it looks correct:

Steps to reproduce:
Export the thing to android and click the play button in the editor, and compare the two versions. The issue should be clear.

Minimal reproduction project:

funnel-new.zip
Please note that I just now realized I misspelled "collectible" everywhere in the project. Oops.

Edit: I just noticed that I can edit this. Removed the old issue.

Or wait, I just googled it, "collectable" seems to be the better word here.
(So I didn't spell it wrong, take that, Grammarly!)

[CenTdemeern1]

Wait, hold on, I just read the description of the Etc vram compression thing.
It doesn't support alpha channels!
That may be the issue for the blue sphere things not showing up?
I don't know how to get around it though, and that doesn't solve the issue of the weird half transparent ball.

Duplicate of #26211. (See also godotengine/godot-proposals#822.)

Update!
I've just established that this doesn't happen on my brother's phone.
It's a Moto E6 Plus phone.

@CenTdemeern1 I feel like this issue is becoming a melting pot of several different bugs. Which bug is not occuring in particular on your brother's phone?

ETC1 doesn't support alpha channel, this is a limitation of the format. No device can lift this limitation.

[CenTdemeern1]

I've dropped the ETC1 "bug" from this thread, it's about the weird looking ball

[CenTdemeern1]

So the kind-of-checkered ball looks normal on my brother's phone

@CenTdemeern1 In that case it is a duplicate of #33633 which has a proposed fix here #33646 :)
