project release , which includes a version of the compositing manager for KDE Plasma 5.15, enhanced with patches to improve interface responsiveness and fix some issues related to the speed of user input reactions, such as input lag. Project developments is licensed under GPLv2.
A ready-made PKGBUILD is available in the AUR for Arch Linux. An option for building KWin with lowlatency patches is being prepared for inclusion in Gentoo ebuild.
This new release is notable for ensuring support for systems with NVIDIA graphics cards. The DRM VBlank code has been replaced with glXWaitVideoSync to provide tearing protection without negatively impacting responsiveness. The original tearing protection in KWin was implemented using a timer and could lead to significant latencies (up to 50ms) in output and, consequently, delayed response during input.
Additional settings have been added (System Settings > Display and Monitor > Compositor) to allow for an optimal balance between responsiveness and functionality. By default, linear animation support is disabled (it can be restored in the settings). A mode for disabling fullscreen output redirection through the transit buffer ("") has been added, which can lead to performance improvements for fullscreen applications.
