Kamil \u0141ysik, who works at NVIDIA, spoke at the XDC 2026 conference with a presentation detailing the results of testing output delays in GNOME 49.7 (mutter) and KDE 6.7.4 (kwin) environments using X.Org Server and Wayland. The code used in the research was published under the MIT license. <\/p>\n

In general, the conclusions indicate that the differences in responsiveness are insignificant and it's hard to identify a single winner. According to Kamil, the most significant impact on delays comes from input processing and the organization of output to the monitor. The technology for adaptive refresh rate change (VRR) was specifically noted, as its activation significantly improved responsiveness. Issues with delays that occurred in previous tests when using XWayland have also been addressed \u2014 no additional delays have been recorded in the new XWayland codebase. <\/p>\n
