However, in the upcoming Mesa 20.2 release, llvmpipe should support GL 4.5. Though do note that software rendering is generally quote slow, anything even beyond very basic use cases should generally use hardware rendering whenever possible. <div class="moz-cite-prefix">On 8/20/20 8:58 AM, Hisham M.

However, Motif is not fully supported on Cygwin since the Microsoft kernel is proprietary and hence a restricted license was given to Cygwin. I tried WSL and Motif there is fully supported, however direct hardware rendering is not supported and has to be done using Mesa software rendering. glxinfo tells me that I have opengl core 3.3 and Mesa 18.3.6 Well searching the net, it says that Mesa 18 and up supports opengl 4.0 and beyond. I am really confused, is there an explanation for such contradiction… Sent from <a href="https://go.microsoft.com/fwlink/?LinkId=550986" moz-do-not-send="true">Mail</a> for Windows 10 </div> <fieldset class="mimeAttachmentHeader"></fieldset> <pre class="moz-quote-pre" wrap="">_______________________________________________ mesa-users mailing list <a class="moz-txt-link-abbreviated" href="mailto:mesa-users@lists.freedesktop.org">mesa-users@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="https://lists.freedesktop.org/mailman/listinfo/mesa-users">https://lists.freedesktop.org/mailman/listinfo/mesa-users</a> </pre> </blockquote> </body> </html>
