Can't run the app on Ubuntu

**Describe the bug**
When I try to run the app from the command line I get the following error:

```
2022-03-06 22:43:47 WARN [/home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-core-0.12.2/src/device/mod.rs:4674] Surface does not support present mode: Mailbox, falling back to FIFO
2022-03-06 22:43:47 WARN [/home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-hal-0.12.4/src/gles/egl.rs:1014] Error in create_window_surface: BadAlloc
thread 'main' panicked at 'Error in Surface::configure: invalid surface', /home/runner/.cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-0.12.0/src/backend/direct.rs:214:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```

The error is from wgpu, a graphics library, failing to create a surface on Ubuntu. Start by checking the app's graphics setup in the main.rs or window creation code. Look for surface configuration and present mode handling. Run with RUST_BACKTRACE=1 to get more details, and see if there are existing issues or documentation about wgpu on Linux. 'Done' means the app runs without the panic.
