The code is written in C++ and is distributed under the GPLv3 license.    <\/p>\n<p>The library handles all low-level operations, including managing graphics buffers, interacting with input subsystems and graphics APIs in Linux, and also offers ready-made implementations of various Wayland protocol extensions. The availability of these components allows developers to save months of work on creating standard low-level elements and instead quickly obtain a ready-to-use composite framework. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/dts-los-angeles\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3823\">server<\/a>, which can be adapted to specific needs and supplemented with the necessary extended functionality. If needed, developers can override the methods provided by the library for handling protocols, input events, and drawing.      <\/p>\n<p>According to the developers, the library significantly outperforms competing solutions in performance. For instance, the composite server example louvre-weston-clone, created using Louvre and replicating the functionality of the Weston project, consumes fewer CPU and GPU resources in conducted tests compared to Weston and Sway, and also achieves consistently high FPS even in complex scenarios.         <center><img decoding=\"async\" alt=\"Louvre 1.0 is available, a library for developing

features of Louvre:  <\/p>\n<ul>\n<li class=\"l\"> Support for operation in multi-GPU configurations (Multi-GPU).\n<li class=\"l\"> Support for multiple user sessions (Multi-Session, TTY switching).\n<li class=\"l\"> A rendering system supporting 2D rendering-based methods (LPainter), scenes (Scene), and views (Views).\n<li class=\"l\"> The ability to use custom shaders and OpenGL ES 2.0 programs.\n<li class=\"l\"> Automatic redraw executed as needed (only when the content area changes).\n<li class=\"l\"> Multithreading, allowing for high FPS with v-sync enabled even when rendering complex scenarios (single-threaded implementations struggle to maintain high FPS due to dropped frames caused by delays waiting for synchronization with the vertical blanking interval (vblank)).\n<li class=\"l\"> Support for single, double, and triple buffering.\n<li class=\"l\"> Implementation of a clipboard for text data.\n<li class=\"l\"> Support for Wayland and extensions:\n<ul>\n<li class=\"l\"> XDG Shell \u2014 an interface for creating and interacting with surfaces like windows, allowing them to be moved, minimized, maximized, resized, etc.\n<li class=\"l\"> XDG Decoration \u2014 rendering window decorations on the server side.\n<li class=\"l\">  Presentation Time \u2014 ensures video playback display.\n<li class=\"l\"> Linux DMA-Buf \u2014 enables the sharing of multiple graphics cards using dma-buf technology.  <\/ul>\n<li class=\"l\"> Support for working in environments based on Intel (i915), AMD (amdgpu), and NVIDIA (proprietary driver or nouveau) drivers.\n<li class=\"l\"> Unimplemented features (on the roadmap):\n<ul>\n<li class=\"l\"> Touch Events \u2014 handling events from touchscreens.\n<li class=\"l\"> Pointer Gestures \u2014 control from touchscreens.\n<li class=\"l\">  Viewporter \u2014 allows the client to perform scaling and edge cropping actions on the server side.\n<li class=\"l\">  Transformation of LView objects.\n<li class=\"l\">  XWayland \u2014 running X11 applications.  <\/ul>\n<\/ul>\n<p>                  <center><img decoding=\"async\" alt=\"Louvre 1.0 is available, a library for developing
