wgpu Validation Error on Startup

[Aligorith]

== Description ==

I freshly cloned the repo, and tried to run it using cargo run. However, the binary promptly panics with the following backtrace:

[ERROR wgpu::backend::direct] Handling wgpu errors as fatal by default
thread 'main' panicked at 'wgpu error: Validation Error

Caused by:

      note: label = `Shadow Opaque 1x`
    parent device is lost

Any ideas on how to go about fixing this?

Hey! Sorry I didn't comment on this sooner. Initially I had a look but I was unable to reproduce your issue.

I've just pushed #19 which completely changes the way viewport rendering works. In particular that "Shadow Opaque 1x" render pipeline is not used anymore. Could you check again to see if the issue is still there? 😄

The whole rendering code is so different at this point that I don't think this issue still applies. I've been able to run recent versions of Blackjack on all major OSs. But please reopen if you still can't run blackjack on your end!
