bevy: testing samples: rendering to device is not working

Hi there

I would like to run the examples and fiddle around with them. But every example which is supposed to render something is failing.

Expected behaviour:

cargo run —example breakout -> run breakout

Current behaviour:

window is unresponsive. and rust (and myself a bit 😉) panicks out backtrace if its of any use:

C:\dev\test\bevy\bevy>cargo run --example breakout
    Finished dev [unoptimized + debuginfo] target(s) in 0.30s

I’m on Win10 with a decent relatively new notebook. It happens as well when i disconnect my external monitor
