I'm inclined to believe this is a glamor bug. The shader does float pattern = texture2D(dash, vec2(dash_offset, 0.5)).w; if (pattern == 0.0) discard; But the texture bound at that time is indeed GL_RED, so of course the result of the texture lookup is always 1.0 no matter what. Fixing the shader (use .r instead) gets a dashed line. I have no idea how that can work anywhere (and even less of an idea why it would be different on intel hw), or maybe glamor uses alpha textures sometimes instead, I couldn't quite figure out how the 8 bit format gets mapped to a gl format in the end... No idea what's the right component for glamor bugs, though...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
