The dotted lines using 2 array length is working (eg 1,1) but when I use a longer array length it does not work (eg 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1). Then the line is showed as dash-dot and not as dot. It used to work with CentOS but now the problem appeared after installilng fedora 26. Any clue? I think this problem is possibly related to glamor module using NOUVEAU. This is a sample code: Pasqual. </pre> <div class="moz-cite-prefix">El 23/01/18 a les 18:24, Chris Wilson ha escrit: </div> <blockquote type="cite" cite="mid:151672827598.13096.12521507555320149163@mail.alporthouse.com"> <pre wrap="">Quoting Clemens Eisserer (2018-01-23 17:03:04) </pre> <blockquote type="cite"> <pre wrap="">Hi, Great to see movement regading this issue. </pre> <blockquote type="cite"> <pre wrap="">It's broken with llvmpipe/softpipe as well. Does it render correctly with glamor on i965?

So it seems the shader is the culprit. </pre> </blockquote> <pre wrap=""> Radial shader (which we think is correct): t = abs(fract(t * 0.5 + 0.5) * 2.0 - 1.0); Linear shader (note unnormalized): distance = abs(mod(distance + _pt_distance, 2.0 * _pt_distance) - _pt_distance); Which makes the same mistake as I did in using mod() instead of the GL definition of fract(). Simplest fix will be to normalize distance and then use the correct transformation from the radial shader. -Chris _______________________________________________ <a class="moz-txt-link-abbreviated" href="mailto:xorg@lists.x.org">xorg@lists.x.org</a>: X.Org support Archives: <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/archives/xorg">http://lists.freedesktop.org/archives/xorg</a> Info: <a class="moz-txt-link-freetext" href="https://lists.x.org/mailman/listinfo/xorg">https://lists.x.org/mailman/listinfo/xorg</a> Your subscription address: %(user_address)s </pre> </blockquote> <div class="moz-signature">-- <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="GENERATOR" content="GtkHTML/4.8.5"> Pasqual Castellón Vicepresident - Software Division skype: pasqual.cadt CADT Software & Drafting, S.L.
