Description
Description
Sometimes, during the configuration of the surface, at start or when resizing, the frames get presented even though they are still written to, which leads to flickering.
The frame rate also increases from 1200 FPS to 2000 FPS which lead me to this conclusion.
Repro steps
Run wgpu water example in release mode with Vulkan backend.
Expected vs observed behavior
The rendering finishes before presenting, even though shouldn't there be triple buffering?
