What's Changed

Fixed

• Wayland CSD maximize/fullscreen geometry (#300) — 5 bugs fixed based on enterprise research (GTK4, winit/SCTK, SDL3/libdecor, GLFW consensus):
  • Title bar at (0, -tbH) on maximize — no longer covers Vulkan content (winit AdwaitaFrame pattern)
  • Fullscreen state parsed from xdg_toplevel states (value 2)
  • ALL decorations destroyed on fullscreen, recreated on restore
  • set_window_geometry negative offset model on maximize (winit/libdecor pattern)
  • ResizeCSD triggers on state change even without size change

Full Changelog: v0.41.10...v0.41.11

Fixed

• Wayland multiwindow (@lkmavi, #292) — 4 bugs:
  • macOS: Show() not called for secondary windows (v0.41.5 regression)
  • Wayland: global callback handles overwritten → per-proxy maps
  • Wayland: closing one window closed both → independent connections
  • Wayland: WaitEvents didn't poll secondary FDs
• Thread panic propagation (@lkmavi) — re-panic on caller instead of silent goroutine death
• macOS GetPoint buffer (@lkmavi) — [4]float64 for goffi HFA return (Go 1.26 -race)

Changed

• Enterprise docs update: README, CONTRIBUTING, ROADMAP, SECURITY
• Open Collective sponsorship badges: https://opencollective.com/gogpu

Contributors

@lkmavi — all 3 code fixes in this release

Changed

• deps: wgpu v0.29.13 → v0.29.14 — missing vertexBuffers in Linux CreateRenderPipeline. All GLES geometry was silently discarded on Linux (vertex attributes never configured). One-line fix found by @lkmavi (wgpu#215/#217).

Changed

• deps: wgpu v0.29.12 → v0.29.13, naga v0.17.13 → v0.17.14
  • GLES enterprise parity: GLSL version propagation, WindowBit-only EGL config tier (Wayland fix), runtime binding fallback GL<4.2, compute barrier, lazy VAO, MSAA validation
  • First Pure Go GLES rendering on Linux Wayland verified (triangle on WSL2 Mesa GL 4.1)

Fixed

• Wayland GLES init (@lkmavi, #292) — renderer 4-phase init split: initInstance → createSurface (GLES) → initAdapterDevice(surfaceHint) → configureSurface. EGL requires surface before GL context.
• Wayland invisible cursor — SetCursor(lastCursor) on wl_pointer.enter (GLFW pattern). Restores last known cursor shape.
• Wayland CSD seat timing — wl_seat in required globals + extra roundtrip for optional late globals.
• Wayland CSD hit-test (@lkmavi) — buttons priority over resize grips at top edge (GNOME/libadwaita pattern).
• Wayland fallback onDraw — Clear(0,0,0,1) for windows without callback so compositor shows the window.
• KDE Plasma AppMenu (@lkmavi) — org_kde_kwin_appmenu protocol for Wayland global menus.
• D-Bus RegisterWindow (@lkmavi) — winID=0 on Wayland (KDE matches by sender PID).
• File dialog key repeat (@lkmavi) — cancel repeat before blocking dialog.

Changed

• deps: wgpu v0.29.9 → v0.29.12 (GLES FFI pointer convention fix — 30+ GL calls corrected, EGL surfaceless/pbuffer, Wayland nativeDisplay fallback, @lkmavi wgpu#210/#213)

Contributors

@lkmavi — 6 out of 8 fixes in this release. Outstanding Wayland + GLES work.

Fixed

• Wayland SIGSEGV (#292) — wl_data_device.data_offer event had NULL wl_message.types array. libwayland's create_proxies() created wl_data_offer proxy with interface=NULL → crash at proxy->object.interface->event_count (offset 0x18). Fix: dataOfferTypes[0] now points to correct wl_data_offer interface struct. Root cause found after 30+ research agents, WAYLAND_DEBUG tracing, strace wire protocol analysis, and libwayland source audit.

Changed

• deps: wgpu v0.29.8 → v0.29.9 (SHM triple-buffer freeze: bufferBusyMap fix + roundtrip_queue dispatch)
• ci: Remove fail_ci_if_error from Codecov (GPG infrastructure issue)

Fixed

• Window creation: hidden-then-show pattern — windows created hidden, shown after GPU init. Eliminates WM_SETFOCUS loss, black flash, and focus race on all platforms. Matches GLFW, Ebiten, SDL3, winit, Flutter.
• Win32: GLFW/Ebiten focus pattern — ShowWindow(SW_SHOWNA) + BringWindowToTop + SetForegroundWindow + SetFocus after handle registration.
• All platforms unified — Show() added to internal PlatformWindow interface. Windows: deferred show. macOS: extracted from CreateWindow. X11: MapWindow deferred. Wayland/Browser: no-op.

Changed

• deps: wgpu v0.29.4 → v0.29.7
  • Fence ordering fix (glFenceSync before glFlush)
  • Fence.Signal returns error (Rust parity)
  • Wayland SIGSEGV fix (#292) — obtainWlShm moved from lazy render-thread init to eager Configure() on main thread. Eliminates race between wl_display_roundtrip and concurrent event dispatch.

Research

• 16 research agents across 3 rounds
• Enterprise references verified: GLFW, Ebiten, SDL3, winit, Flutter, Qt6
• Raymond Chen: "Saving the window handle too late"
• Wayland wl_proxy.display at offset 0x18 confirmed via libwayland struct layout

Fixed

• Wayland Vulkan: app event queue separation (ADR-041 Phase 4, #292) — all app Wayland objects moved to custom wl_event_queue. Default queue left for Mesa Vulkan WSI. Prevents dispatch from firing Mesa's internal wl_buffer.release callbacks. Enterprise pattern from GLFW/SDL3.
• Wayland CSD thread safety — DispatchCSDEvents() holds displayMu for thread-safe wl_display_flush.

Changed

• deps: wgpu v0.29.4 (Wayland GLES wl_egl_window + Software wl_shm + VK_ERROR_SURFACE_LOST), goffi v0.5.3

Full Changelog: v0.41.3...v0.41.4

Fixed

• Wayland SIGSEGV in vkQueuePresentKHR (ADR-041, #292) — two fixes:
  • Configure gate: blocking WaitForConfigure() loop (SDL3/winit pattern). xdg-shell spec requires xdg_surface.configure before first buffer attach.
  • Display thread safety: displayMu mutex serializes wl_display access between main thread (event dispatch) and render thread (Vulkan WSI). DisplayLocker optional interface — no-op on X11/Windows/macOS/WASM.

Fixes crash on all Wayland compositors (GNOME, KDE, Sway) with any GPU vendor. Tested users: please verify with go get github.com/gogpu/gogpu@v0.41.3.

Full Changelog: v0.41.2...v0.41.3

Fixed

• D-Bus flag: NO_REPLY_EXPECTED was 0x02 (NO_AUTO_START), now 0x01 — wrong flag could prevent AppMenu registrar from starting on socket-activated desktop environments.
• DRY refactor: dbusAssembleMsg extracted as shared function (dbus_linux.go), eliminates duplication between file dialog and menu D-Bus code.
• stopCh shutdown logging — serve() now distinguishes intentional shutdown from unexpected connection loss.
