Hi, Please review my fix-suggestion for the problem described below available at: http://cr.openjdk.java.net/~ceisserer/fix11/webrev.03/ A testcase is available at: http://cr.openjdk.java.net/~ceisserer/fix11/TextCompTest.java
Problem description: When rendering Text with AlphaComposite.SrcIn and Src/SrcIn with EA, the accelerated D3D/OGL pipelines render black boxes arround individual glyphs. As far as I can see, this is caused by an invalid check during pipeline validation: /* CompositeType.SrcNoEa (any color) */ - (sg2d.compositeState <= SunGraphics2D.COMP_ISCOPY && - sg2d.paintState <= SunGraphics2D.PAINT_ALPHACOLOR) >From my understanding the check should allow for using the accelerated text pipeline for AlphaComposite.SRC when a color is used as source. However, as is the check also accepts the composition rules CLEAR, SRC, SRCIN regardless of extra alpha. Fix description: The fix makes the check strikter to explicitly check for comp-rule==Src and the currently set extra-alpha == 1. It only fixes the issue for the OpenGL pipeline, but the changes should apply 1:1 for the D3D pipeline. Thanks, Clemens
