View no longer updating after CefBrowserHost::WasResized

[blattersturm]

To support changing video modes dynamically, our application uses WasResized to resize the existing browser view upon detection of a mode change.

However, with this patch set, usage of WasResized (and returning a different resolution in GetViewRect) will stop updating the browser view after resizing it. (OnAcceleratedPaint no longer being called, initial debugging inside Chromium shows that no BeginFrame calls are being generated anymore)

Just to chime in I can say that we don't experience this issue. For us calling CefBrowserHost::WasResized triggers (at some later point) a call to OnAcceleratedPaint with a new shared_handle. Much like the example application we then check whether the new one matches our cached one and recreate the texture (with the new size) if it doesn't.

That's weird - what flags are you using in your CefApp::OnBeforeCommandLineProcessing? It might also be something else we're doing is conflicting with this... 😕

disable-gpu-vsync is the only one we're using at the moment. It shows the same behavior regardless if I include that one or not though.

Ah, thanks! We had in-process-gpu in there due to a prior accelerated rendering patch, which seems to conflict with disable-gpu-vsync being used at the same time.
