CI / build (push) Failing after 0s
The full view is now the default. While the renderer process covers the whole view (Channel::covering, set after each frame it presents), the adapter skips the client's renderer's clears and draws, decided per frame; the client's renderer still gets state and resources, and draws again as soon as the renderer process stops covering the view. The client's window no longer gets WS_CLIPCHILDREN: the client draws when its window gets WM_PAINT, which a window entirely covered by clipped children never gets (it fell to about one frame a second). The flip model swap chain shows above the client's drawing anyway. Co-Authored-By: Claude Opus 5.5 <[email protected]>
