Bug: V8 graphics tint applied in a weird way

[jakerdy]

Current Behavior

Hi, I finnaly decided to port my app to V8 and encounter couple problems.

First problem that I got, it's different tint behaviour on Graphics. In v7 tints applied via color multiplication. In v8 it works somehow differetly, which makes unpredictable results in most cases.

Here you could see this effect:

Is this some kind new feature that wasn't described in migration guide and changelogs, or it is a bug?

Expected Behavior

V8 Graphics tints should be multiplicative. If tint is black, graphics also should be black.

Steps to Reproduce

V8 playground: https://www.pixiplayground.com/#/edit/LLWPYftOAq044gn7sSoxV
V7 playground: https://www.pixiplayground.com/#/edit/IDHn7Kt2sVujHnXA512i4

Environment

• pixi.js version: e.g. 8.1.0
• Browser & Version: e.g. Chrome 124
• OS & Version: e.g. Windows 10

Actually, every single non white renderable ellement where tint was applied looks differently.

Here couple screens from my app:

Pixi v7.4.0:

Pixi v8.1.0:

Text movement is a second problem, I will report it as separate issue.
