[3.0] caopengllayer: fix wrong fullscreen size
When transitioning to fullscreen, the codepath for non-live resize was used and did not trigger rendering here. As the size if now handled by the window however, this resulted in a wrong size as it was never actually updated. To prevent that, always render with the proper size from the layer regardless if we are in live-resize or not.
Fixes #27276 (closed)
