Description of the feature or fix

The open-source community reported a blend issue of GPU-Arm2D found in LVGL8.3.11.
For blend-normal-with-mask-and-opa, the opa has no effects due to using the wrong API of arm-2d.

Checkpoints

• Update the Documentation if needed.
• Add Examples if relevant.

Looks good to me.

Off topic : could a test catch this issue?

@GorgonMeducer Does Arm2D have a desktop compatible version that we can use in our tests?

[GorgonMeducer]

@kisvegabor YES. Arm-2D is compatible with x86. We even have a VSCode+Make+SDL project:

For use with LVGL, you only need the folder Arm-2D/Library, not anything else.

That's great! Have you already tried the lv_demo_render with on PC with Arm2D? Here are the tests for SW render.

[GorgonMeducer]

@kisvegabor NOT yet. Would try it later.
