When the resolution changes, the driver internally updates the width and height, but the client continue to queue buffers with the older resolution until the last flag is received. This results in a mismatch when the buffers are prepared, causing failure due to outdated size.
Introduce a check to prevent size validation during buffer preparation if a resolution reconfiguration is in progress, to handle this.
