You say:

with the CEF sample cefclient --off-screen-rendering-enabled --multi-threaded-message-loop
it does not reproduce the issue because CefRefPtr::WasResized is still called in the CEF_UIT thread so there is no task posted, the work is executed synchronuously.

This suggests that your timing of calling WasResized and returning updated values from GetViewRect may be incorrect. You need to make sure that GetViewRect is returning the correct value when WasResized actually executes.

@magreenblatt Thanks for your quick answer. But after a huge debug session in our side, there is something strange which happens in cef, you can reproduice easily with your cefclient. (see https://magpcss.org/ceforum/viewtopic.php?f=6&t=20038&p=56405&hilit=CEF129#p56405)
