[QUOTE="MCelliotG, post: 1069624, member: 404726"] I have my friend send me two screencaps, so you can see the problem in detail. In general, SF8008's png driver does not blend images well when they are overlayed, and renders unecessary grey when there is a gradient to alpha clear. Look at example 1. On the left we have the correct behaviour on all other STBs and on the right the erroreous blending and rendering on SF8008. [ATTACH type="full"]123745[/ATTACH] As you can see the colors are way too greyish and faded, especially on the blue/turquoise gradient png graphic, also the fade towards the clear background is also grey. Around the white pngs there is also a grey shadow where it should be a light blue shadow that should be barely noticeable. Also, on the lower right, the transparent black png is below in z position the escalating transparent blue and should not be blended into it (not even flagged to blend in the skin.xml). These are also two different screens that should not blend into each other. Since the blue line is over in z position it should overlap the black one and not blend into it. Moreover, the blue selector is not fading to clear as it is expected but renders an undesired blue color. The clock on the top right is even a greater example. It should appear transparent black but it's completely grey. The same fade error and grey tones are apparent in the second example. [ATTACH type="full"]123746[/ATTACH] The left transparent blue panel should fade to a clearer transparency, but SF8008 renders a grey color. Also the grey contour shows even more on black background. Now, when a skin is not using png transparency or not png overlays, the user may never notice the issue, but that does not mean that pngs are rendered correctly. This behaviour reminds me of the rendering of 8bit alpha transparency! On the above examples, all graphics shown (except the white ones) are 32bit transparent. Thus, it seems SF8008 is unable to render 32bit transparency correctly, it downgrades it to 8bit quality. And blends all graphics by setting the alphatest flag to blend overriding all other skin flags. [/QUOTE]
