Configuration

Dear ImGui 1.89.6 WIP (18954)
--------------------------------
sizeof(size_t): 8, sizeof(ImDrawIdx): 2, sizeof(ImDrawVert): 20
define: __cplusplus=199711
define: _WIN32
define: _WIN64
define: _MSC_VER=1935
define: _MSVC_LANG=201402
--------------------------------
io.BackendPlatformName: imgui_impl_glfw
io.BackendRendererName: imgui_impl_opengl3
io.ConfigFlags: 0x00000003
 NavEnableKeyboard
 NavEnableGamepad
io.ConfigInputTextCursorBlink
io.ConfigWindowsResizeFromEdges
io.ConfigWindowsMoveFromTitleBarOnly
io.ConfigMemoryCompactTimer = 60.0
[snip]

Issue:

With io.ConfigWindowsMoveFromTitleBarOnly window resizes incorrectly when mouse touches top of window draw-able area (top of OS Window).

Reproduces in Demo on GLFW+OpenGL3 example in Dear ImGui on Windows, also observed on SDL2+OpenGL3 on Ubunto Linux.

Standalone, minimal, complete and verifiable example:

No new code needed to reproduce
