wgpu: How to avoid Timeout errors
My tutorial will occasionally encounter a SwapChainError::Timeout during normal execution. Currently I’m just kidding the error out, but I was wondering is there a way to avoid this error? Is there someway to sync the simulation with the refresh rate of the screen?

Running from the latest master (e5142b3c) eliminates the OOM errors, so setting
PresentMode::MailboxorPresentMode::Immediateruns without error.PresentMode::Fifois the same as before with timeout errors but no OOM errors.I can try more things locally if that’d be helpful.
The timeout could happen if our back-pressue doesn’t work as expected. I.e.
get_current_framedoesn’t actually make CPU wait for GPU to process the old frame.
