Hello again,
At least the radeonhd-version shipped with Ubuntu-9.04 seems to fall back to software when compositing with a source that has: - Transformation applied - "fast" filte - RepeatNone.
JXRenderMark seems to confirm my findings, it is available at: http://78.31.67.79:8080/jxrender/RenderMark.html
If I use RepeatPad + Mask + "good" filter everything seems fine. Is this a known problem, or should I open a bug-report about it?
Add some debugging to R600CheckComposite() and see what's causing it to fall back. I suspect you are hitting the following in R600CheckCompositeTexture(): /* for REPEAT_NONE, Render semantics are that sampling outside the source * picture results in alpha=0 pixels. We can implement this with a border color * *if* our source texture has an alpha channel, otherwise we need to fall * back. If we're not transformed then we hope that upper layers have clipped * rendering to the bounds of the source drawable, in which case it doesn't * matter. I have not, however, verified that the X server always does such * clipping. */ /* FIXME R6xx */ if (pPict->transform != 0 && !pPict->repeat && PICT_FORMAT_A(pPict->format) == 0) { if (!(((op == PictOpSrc) || (op == PictOpClear)) && (PICT_FORMAT_A(pDstPict->format) == 0))) RADEON_FALLBACK(("REPEAT_NONE unsupported for transformed xRGB source\n")); } It's not compliant if you remove the check, but I haven't seen any issues either. I'm not really a render expert however. Alex -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
