The OpenGL2 backend was immediately destroying textures on
ImTextureStatus_WantDestroy without checking tex->UnusedFrames > 0,
unlike ALL other backends (OpenGL3, DX11, DX12, Metal, Vulkan, WebGPU)
which defer destruction until the texture is no longer in use by the GPU.
This could cause a use-after-free if the texture was still referenced by
in-flight draw commands when it was destroyed.
Fix: Add '&& tex->UnusedFrames > 0' to the WantDestroy check, matching
the pattern used by OpenGL3, DX11, Metal, Vulkan, and WebGPU.
Android backend (imgui_impl_android.cpp):
- After AMOTION_EVENT_ACTION_UP for FINGER/UNKNOWN input, clear mouse
position via AddMousePosEvent(-FLT_MAX, -FLT_MAX). This prevents buttons
from staying in hovered/pressed state after touch release. On touchscreens
there is no hover — the pointer is gone after release. (#6627)
- Omar confirmed this is the right approach in issue comments: 'the backend
should submit a mouse leaving event after the touch release'
SDL2 backend (imgui_impl_sdl2.cpp):
- Restore SDL_StartTextInput()/SDL_StopTextInput() in the IME handler
(ImGui_ImplSDL2_PlatformSetImeData). These calls were removed in a7703fe6
due to concerns about desktop IME, but are required on Android to show
the on-screen keyboard when InputText is focused. The equivalent fix was
already applied to SDL3 in fab96a6e but not SDL2. (#7636)
Both fixes are referenced in docs/CHANGELOG.txt.
The OpenGL2 and OpenGL3 backends set GL_UNPACK_ROW_LENGTH=0 and
GL_UNPACK_ALIGNMENT=1 during texture creation and updates, but
never restored the original values. This corrupted the calling
application's pixel store state when ImGui created or updated
textures mid-frame (e.g., dynamic font atlas updates).
Fix: Backup GL_UNPACK_ROW_LENGTH and GL_UNPACK_ALIGNMENT at the
start of UpdateTexture(), and restore them at the end.
This resolves the FIXME in ImGui_ImplOpenGL3_UpdateTexture():
'FIXME: Consider backing up and restoring'
Issues: #8802 (original UNPACK_ALIGNMENT change), #9473 (this fix)
The make command was failing because LDFLAGS+='' doesn't properly override
the Makefile's appended flags. Instead, use sed to:
1. Replace shell_minimal.html with shell_imgui_xl.html
2. Uncomment the -sSINGLE_FILE line
Also added keep_files: true and destination_dir: wasm to the deploy step
so the existing gh-pages content is preserved.
Add .github/workflows/deploy-wasm.yml that:
- Installs Emscripten SDK on ubuntu-latest
- Builds example_sdl2_opengl3 with Makefile.emscripten using -sSINGLE_FILE
(all WASM+JS embedded in a single .html file, no separate .wasm/.js)
- Uses custom shell_imgui_xl.html with loading spinner and WebGL context
loss handling
- Deploys to gh-pages/wasm/ directory via peaceiris/actions-gh-pages
The resulting live demo at turtle-pb.github.io/imgui_xl/wasm/index.html
will show the ACTUAL Dear ImGui demo window running in the browser via
WebAssembly — not a canvas simulation, but real compiled C++ ImGui.
Triggers on pushes to master that touch ImGui source files, the SDL2/
OpenGL3 backend, the example, or the shell template.
Also supports manual workflow_dispatch.
bindings/go/:
- imgui_bridge.h/.cpp: Thin C API bridge (extern C) wrapping C++ ImGui
- imgui.go: Go cgo package (CreateContext, NewFrame, Begin, Button,
SliderFloat, SliderInt, Checkbox, ColorEdit3, Text, Combo, etc.)
- go.mod: Module definition
- README.md: Full docs with usage, building, and API reference
examples/example_golang/:
- main.go: Null-mode example showing ImGui from Go
- go.mod: Module with replace directive for local bindings
- Makefile: Build/run/clean targets
Go 1.26.5 verified working on this host. CGO_ENABLED=1 required
(plus a C++ compiler like g++ for the bridge compilation).
Add a fully self-contained Pixel 8 Pro phone simulator that showcases
Pixel OS capabilities in any browser. Includes:
- Working menu bar (File, View, Tools, Help) with keyboard shortcuts
- Lock screen with live clock, notifications, fingerprint/swipe unlock
- Home screen with Material You design, Google search, weather widget
- 7 functional apps: Phone, Messages, Camera, Settings, Clock, Photos, Browser
- Quick Settings panel with 8 toggle tiles + brightness slider
- Recents app switcher
- Dark mode toggle and 6-theme color switcher
- Mouse + touch gesture support (swipe up for home, swipe down for QS)
- Bottom status bar showing demo state
All functions work — every menu item, button, toggle, and gesture
is wired to a real handler. No build step, no dependencies.
Part of imgui_xl examples.
