Linux/i3: screen artifacts and crash

[theduke]

On Linux, with the i3 tiling WM, iced does not work correctly.

When running a example or a custom project, the window shows weird black/white artifacts and the program crashes with a assertion failure after moving the mouse a round a bit.

thread 'main' panicked at 'assertion failed: `(left == right)`
  left: `0`,
 right: `1`', /home/theduke/.local/share/cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-native-0.4.1/src/hub.rs:120:9

Hey, sorry to hear that.

Do the wgpu examples work for you? Some people have been able to fix glitches and crashes by updating the graphics drivers, specially if you have an integrated device (see #98).

Do the wgpu examples work for you?

Nope, seems to be a wgpu issue. Apparently doesn't work with Vulkan/AMD Ryzen 3000 APUs right now (my drivers are up to date).

[theduke]

Ah I got it working in the end.

For others in the same situation, the required Arch packages for a AMD Ryzen 5 3400G APU (Radeon Vega Graphics) are:

• mesa
• amdvlk
• vulkan-radeon
