Public bug reported: Dear maintainer,
Recently I discovered that KWin's environment variable KWIN_USE_INTEL_SWAP_EVENT=1 makes a huge difference for latency/smoothness It was supposed to be enabled in KWin 5.18 but due to "organizational issues with KWin development" Roman Glig reverted his commits. Improvement of that setting reported users with different GPUs https://bugs.kde.org/show_bug.cgi?id=344433#c27 https://bugs.kde.org/show_bug.cgi?id=415262#c2 However it introduces problems when compositor state changes. Roman Glig fixed it with really simple patch (which unfortunately also was reverted). https://phabricator.kde.org/D26090 Could you please cherry-pick it for KWin packages? Source is trusted, fix confirmed and currently could be easily applied (attached slightly adapted patch). Thanks. ** Affects: kwin (Ubuntu) Importance: Undecided Status: New ** Patch added: "Original patch is slightly different, here's adapted version" https://bugs.launchpad.net/bugs/1876528/+attachment/5365406/+files/reset_buffer_swap_state_on_stop.patch ** Description changed: Dear maintainer, Recently I discovered that KWin's environment variable KWIN_USE_INTEL_SWAP_EVENT=1 makes a huge difference for latency/smoothness It was supposed to be enabled in KWin 5.18 but due to "organizational issues with KWin development" Roman Glig reverted his commits.
