This gives comparable performance<br>to Trinity-Konqueror, with the advantage of being way closer to Firefox<br>in both UI design and codebase, so pages that work fine in Firefox<br>should work fine in Pale Moon as well - something I wouldn't want to<br>take for granted with Trinity-Konqueror.<br><br>I have uploaded two demo videos showing the performance of Firefox (with<br>XRENDER only, not cairo) vs. Trinity-Konqueror and vs. Pale Moon:<br><br>Firefox (left) vs. TDE-Konqueror (right): https://youtu.be/GfTVhX0UT8M<br>Firefox (left) vs. Pale Moon (right): https://youtu.be/kilDivhvMZw<br><br>I decided to talk to the Pale Moon developers on IRC and it turns out<br>they plan to revamp their core component<br><http://personal.mattatobin.com/image/capture/c4d873f0-9048-4523-8abf-ba5763067c9a.jpg><br>some time next year ("port Pale Moon to the up and coming Unified XUL<br>Platform from the<br>current platform code we have now").<br>The one person I talked to in particular, Matt A. Tobin, suggested that<br>the drop in performance came with the drop of support for GTK2.<br>The Pale Moon developers would be interested in keeping GTK2 support<br>even in their new core component, but would need some cash and<br>especially some additional manpower in the form of skilled coders.<br><br>So this is a call for help:<br><br>- If you're a company that uses X2Go and is interested in supporting<br> Pale Moon development, either financially or by assigning your own<br> coders to the project, please let me know.<br>- If you're a professional coder interested in working on Pale Moon<br> as long as you get paid for it, please let me know.<br>- If you're a volunteer coder that wants to work on Pale Moon just for<br> the greater good of all, please let me know too.<br><br>-> I will be coordinating all efforts from the X2Go side of things.<br><br>Any questions, suggestions, comments, etc. please follow up either in<br>X2Go-Dev or via PM.<br><br>Kind Regards,<br>Stefan Baur<br><br>-- <br>BAUR-ITCS UG (haftungsbeschränkt)<br>Geschäftsführer: Stefan Baur<br>Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364<br>Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243<br><br></body></html>
