Just a few grammar/spelling things I noticed in the comments. :)
From testing, this only occurs with the tiled compositor. Full Frame compositor doesn't have the black pixels.
‘ CompositorNodeSceneTime’ and ‘ CompositorNodeTime’ are both listed twice.
Not a full triaging due to time constraints, but noting that shadow calculation is involved, as unchecking Cast Shadow under the light settings will make the diffused squares reflect light.
@Ha_Lo Playing around with your file on the frame in the screen shot reveals another issue: As far as I can tell, the blending mode is applied to the entire area before cropping, which is why the…
It appears that it was:
scol[3] = unit_float_to_ushort_clamp(mcol2->a * (1.0f / 255.0f))
prior to that commit.
This is actually a limitation of PNG files themselves. Blender's render engines, including Cycles, output associated (premultiplied) alpha. The PNG specification states that PNG files use…

Hello @Ahmed-Mohammed-Abd-El-Sabour
If you change the graph editor to the dopesheet, you can see that there is only one track that is continuous between the 2 keyframes: Track 17. You need 7…
My OS is Windows 11 pro but for some reason the Help > Report a Bug feature mistakenly put "Windows-10-10.0.22621-SP0 64 Bits" in the ticket. anyway probably trivial detail.
Microsoft, for…
Perhaps the bug is that if the colour channels are negative, then the alpha over node doesn't respect the alpha's value? Alpha 0 should mean the alpha over uses the background completely, …
Additionally, you generally need the curve to be extend extrapolated for correct results on the RGB channels. So setting it to Extend horizontal isn't possible.
Ah yes, I was only just…
The curve node isn't modifying the alpha channel. Looking at the output of the curve node alone (by right-clicking the alpha section in the Image Viewer window), you can see that Alpha is still…
Thank you for the report @3di.
The curve node is set to Extend Extrapolated. The line continues straight, making the color at X=0 negative, instead of 0 as expected. Background of 1.0 white…
