Details:
There may have been changes to the win32 backend lately relating to forced wide char usage, there seems to be an inconsistency in the UnregisterClass call, which should also be wide: UnregisterClassW
Screenshots/Video:
No response
Minimal, Complete and Verifiable Example code:
Should look like this imho:
static void ImGui_ImplWin32_ShutdownMultiViewportSupport()
{
::UnregisterClassW(L"ImGui Platform", ::GetModuleHandle(nullptr));
ImGui::DestroyPlatformWindows();
}
