`PointLight2D` blend mode doesn't work #91279

Open Firepixel85 opened 5 months ago

Firepixel85 commented 5 months ago

Tested versions

Reproducible since Godot 4.0.4 stable

System information

MacOS 12.3.1 Macbook Air onboard graphics (Intel 6000 HD)

Issue description

When using a PointLight2D, all blend modes add light, I have tested it to only work with my mac (it works fine on PC)

Steps to reproduce

On a new scene add a Sprite2D or any visible to the camera node
Add a PointLight2D and make sure it effects the Sprite2D
Set the Blend Mode to Subtract or Mix and adjust the Energy so the effect is visible
Observe the weirdness

Minimal reproduction project (MRP)

Please try with a more recent version, 4.0 is no longer supported, please try with 4.1.4 or 4.2.2, please specify which versions you've tested if you've tried others than 4.0.4

Tested on a M2 MBP using 4.3 (recent dev build) and can't reproduce. This is likely something that has been fixed since 4.0.4.

Subtract

Add

Mix

Thanks for the responses, I am aware this isn't an issue for most systems and as stated above I've only gotten it to bug out on my mac, I believe the problem isn't the blend mode but how godot interacts with my graphics (intel 6000 HD) I have tested the issue up to version 4.3 dev 5 here are the results from my end: 4 3dev5

Confirmed when using a 2015 MBP (MacOS 12.6.1 Intel Iris 6100)!

The issue remains even when switching to the angle backend
