If you run testautomation --renderer opengles2, it will fail some of the rendering tests:

--filter render_testPrimitives
--filter render_testBlit9Grid
--filter render_testBlitColor

Alpha blending 50% 255 is outputting 187 instead of 127-128.
@slouken slouken added this to the 3.2.10 milestone Mar 6, 2025

As far as I can tell this has always been broken. I tested all the way back to 2.0.20.

Except this passed on my Linux box. Maybe this is an AMD driver bug?
