When I pick one of the corners of the window and move my mouse around for a couple of seconds, and then let go of the mouse button, the CrossWindow freezes up completely and I have to wait a couple seconds more for it to render/respond again.
The problem is very likely caused by how event-queueing is implemented (i.e. class EventQueue) and how it is used by the Window class.
The input events seem to get queued up during the resizing of the window, and CrossWindow only starts actually processing the events (emptying the queue) when the mouse button is released.
This also means that no content is visible in the window while it is being resized, but only white/black artifacts are shown.
(Ideally the resizing would happen in realtime, and content will be shown at all times)
PS:
I had to fix several (minor) compile issues before I could get the example running, mainly a hwnd field getting replaced by a getHwnd() function
The DIRECTX12 renderer does not render the triangle, there are D3D12 error messages logged for each rendered frame (see below)
The DIRECTX11 renderer does work, but it also logs D3D11 error messages (see below)

I am testing CrossWindow on Windows 10, mainly the 04-cross-platform-hello-triangle
When I pick one of the corners of the window and move my mouse around for a couple of seconds, and then let go of the mouse button, the CrossWindow freezes up completely and I have to wait a couple seconds more for it to render/respond again.
The problem is very likely caused by how event-queueing is implemented (i.e.

The input events seem to get queued up during the resizing of the window, and CrossWindow only starts actually processing the events (emptying the queue) when the mouse button is released.This also means that no content is visible in the window while it is being resized, but only white/black artifacts are shown.
