SoftFever	be2a2d4873	WIP: Add native Wayland support for Linux (#13197) ... * Add runtime display backend detection for Wayland support Add LinuxDisplayBackend utility to detect X11 vs Wayland at runtime using GDK_IS_X11_DISPLAY / GDK_IS_WAYLAND_DISPLAY macros. This is the foundation for removing the forced GDK_BACKEND=x11 and enabling native Wayland support. - New files: LinuxDisplayBackend.hpp/.cpp with get_linux_display_backend(), is_running_on_wayland(), and is_running_on_x11() - Propagate wxHAVE_GDK_X11 / wxHAVE_GDK_WAYLAND from FindGTK3.cmake as compile definitions to libslic3r_gui - No-op on non-Linux platforms (returns Unknown / false) * Fix Phase 1 code quality: pragma once, source ordering, static cache * Make X11 initialization conditional for Wayland support Remove the unconditional GDK_BACKEND=x11 force that blocked native Wayland. Replace with conditional logic: - EGL safety fallback: re-force X11 only when wxUSE_GLCANVAS_EGL is off and WAYLAND_DISPLAY is set, with a warning log - XInitThreads() only called when DISPLAY is set (X11 in use) - __GLX_VENDOR_LIBRARY_NAME only set when DISPLAY is present (GLX-specific) - WEBKIT_DISABLE_COMPOSITING_MODE only set under XWayland (both DISPLAY and WAYLAND_DISPLAY present) - Guard X11/Xlib.h include with __has_include for robustness - Restore display validation to accept either DISPLAY or WAYLAND_DISPLAY This is Phase 2 of the Wayland support plan. * Fix Phase 2: safer EGL macro check, add clarifying comments * Add GLAD2 library and replace GLEW linkage in build system Set up GLAD2 as a static library to replace GLEW for OpenGL loading. GLAD2 supports both GLX and EGL, which is required for Wayland support. - Create src/glad/ with pre-generated GLAD2 sources (GL 4.6 compat) - Add src/glad/CMakeLists.txt building glad as a static library - Wire glad into src/CMakeLists.txt before libvgcode - Modify libvgcode to use shared glad for GL path (keeps local copy only for GLES2/Emscripten) to avoid duplicate symbol conflicts - Replace GLEW::GLEW with glad in libslic3r_gui link libraries Note: GLEW is kept in deps for OpenCSG. Code migration from GL/glew.h to glad/gl.h headers will follow in Phase 3B+3C. * Fix Phase 3A+3D: libvgcode GLAD include, dead files, dlopen dep, OpenGL link var * Migrate from GLEW to GLAD: replace headers and API calls across codebase Replace all #include <GL/glew.h> with <glad/gl.h> across 49 source files. Migrate GLEW API calls to GLAD equivalents: - glewInit/glewExperimental -> gladLoaderLoadGL() - GLEW_EXT_* / GLEW_ARB_* extension checks -> GLAD_GL_EXT_* / GLAD_GL_ARB_* - Remove GLEW-specific EGL/GLX mismatch #error guards (not needed with GLAD) - Replace unavailable EXT symbols with core GL equivalents in GLCanvas3D.cpp (GL_MAX_SAMPLES, glRenderbufferStorageMultisample, glBlitFramebuffer, GL_READ/DRAW_FRAMEBUFFER) - Update log messages from glewInit to gladLoadGL * Fix Phase 3B+3C: remove GLEW find, clean EXT symbols, update attribution - Remove find_package(GLEW) block from root CMakeLists.txt since GLEW is no longer linked by any main application code - Remove "glew" from SLIC3R_STATIC option description - Replace all remaining EXT framebuffer symbols with core equivalents in render_thumbnail_framebuffer_ext and _rectangular_selection_picking_pass - Update AboutDialog credits from GLEW to GLAD * Enable EGL in wxWidgets and add runtime GLX/EGL selection for Wayland - Set wxUSE_GLCANVAS_EGL=ON in wxWidgets build and Flatpak manifest - Add PreferGLX() call on X11 sessions for driver compatibility - Remove Phase 2 safety fallback (EGL is now always compiled in) - Guard SwapBuffers against hidden canvases to prevent Wayland stalls * Fix Phase 4: move PreferGLX to app startup, fix FPS counter guard Move wxGLCanvas::PreferGLX() from OpenGLManager::create_wxglcanvas() (static initializer) to GUI_App::on_init_inner() before any wxGLCanvas is constructed. This prevents a race where SkipPartCanvas could trigger wxGLBackend::Init() before the GLX preference is set. The new location also adds explicit is_running_on_wayland() detection with a warning for unknown backends. Move increment_fps_counter() inside the IsShownOnScreen() guard so FPS is only counted when a frame is actually swapped. * Update GLFW from 3.3.7 to 3.4 for runtime Wayland/X11 backend selection Replace the compile-time GLFW_USE_WAYLAND flag (which locked to a single backend) with GLFW 3.4's GLFW_BUILD_WAYLAND + GLFW_BUILD_X11 flags that build both backends and auto-select at runtime based on the available display server. This enables the CLI thumbnail renderer to work on both Wayland and X11 sessions without separate builds. * wayland: Fix UI call sites that rely on global screen coordinates On Wayland, wxGetMousePosition() returns (0,0) and SetPosition() is a no-op for top-level windows. Fix the highest-impact call sites: - GLCanvas3D: Use cached m_mouse.position from event handlers instead of wxGetMousePosition() + ScreenToClient() in get_local_mouse_position() - Plater: Use event-relative coords via ClientToScreen(e.GetPosition()) instead of wxGetMousePosition() in 3 leave-window handlers - BBLTopbar: Use event.GetPosition() and FindToolByPosition() directly in mouse handlers instead of wxGetMousePosition()/FindToolByCurrentPosition() - Search: Use focus-based dismiss logic on Wayland instead of wxGetMousePosition()-based rect checks in SearchDialog and SearchObjectDialog - GUI_App: Skip SetPosition() in window_pos_restore() on Wayland where it is a no-op; still restore size and maximize state - Button: Position tooltip relative to button widget via ClientToScreen instead of wxGetMousePosition() * Fix SearchDialog Wayland dismiss: guard against search_line focus * flatpak: Add Wayland socket permission for native Wayland support * spec * Fix crash on Wayland when wxWidgets lacks EGL support Restore the safety fallback that forces GDK_BACKEND=x11 when wxWidgets was not built with wxUSE_GLCANVAS_EGL=ON. Without this, the GLX backend tries to access a non-existent X11 display on native Wayland, crashing in wxGLCanvas::IsDisplaySupported() with SIGSEGV at offset 0xe4. Also add a defense-in-depth guard in detect_multisample() that skips the IsDisplaySupported call entirely on Wayland without EGL. Root cause: deps/wxWidgets must be rebuilt after enabling EGL. The compile-time check in OrcaSlicer.cpp detects the mismatch and falls back safely. * Fix EGL detection: use wxHAS_EGL instead of wxUSE_GLCANVAS_EGL wxUSE_GLCANVAS_EGL is a CMake build option, NOT a C++ preprocessor macro. The actual macro defined in wxWidgets setup.h is wxHAS_EGL. All compile-time EGL checks were using the wrong macro, causing the safety fallback to always trigger even with a properly built EGL-enabled wxWidgets. * Fix GL function pointers invalidated on Wayland/EGL gladLoaderLoadGL() dlopen's libGL.so.1 to resolve GL function pointers via dlsym, then immediately dlclose's the handle. On X11/GLX this is fine because the GLX context keeps libGL.so mapped. On Wayland/EGL, nothing else holds libGL.so open, so dlclose unmaps it and all function pointers become dangling — causing SIGSEGV on the first GL call. Fix: on Wayland, use gladLoadGL(eglGetProcAddress) which resolves function pointers through the EGL loader without opening/closing libGL.so. * fix crash on start and various rendering issues * fix crash on close * small refactor * move GPU selection to desktop file * clean up a bit * clean up more * fix appimage error	2026-04-13 19:45:39 +08:00
