cargo run --example tour crashes with (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

[dotjpg3141]

Related (duplicate?) of #98.

I'm trying to run cargo run --example tour on Windows 10, but it crashes:

$> cargo run --package tour
    Finished dev [unoptimized + debuginfo] target(s) in 0.50s
     Running `target\debug\tour.exe`
error: process didn't exit successfully: `target\debug\tour.exe` (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

I have an additional monitor connected to my laptop, which is my primary display:

1. Laptop monitor
2. Additional monitor (primary display)

However, I can start the application successfully by I either making my laptop (1) the primary display or by disconnecting my additional monitor (2) (which makes my laptop monitor also the primary display I guess).

I have these graphic cards with the latest drivers installed:

• Intel(R) HD Graphics 530
• NVIDIA GeForce GTX 970M

Iced is using the Vulkan renderer and is crashing somewhere here trying to create the swap chain.

I have tested the cube example in wgpu-rs which worked fine for me.

Thanks for the report!

Could you try the game_of_life or solar_system examples? Unlike the tour, they should always choose the most powerful GPU.

[dotjpg3141]

Both work fine for me.

[andy5995]

Both work fine for me.

For me, cargo run works if I'm in iced/examples/tour, otherwise:

andy@oceanus:~/src/rust/iced$ cargo run --example tour
error: no example target named `tour`
andy@oceanus:~/src/rust/iced$ uname -a
Linux oceanus 4.19.0-10-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux

[Absolucy]

I'm getting a similar error: (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION).

Using the iced_glow renders works perfectly fine.
