test run_test_with_new_context fails

[GreatGodOfFire]

When I run cargo test the test test fails with the following error:

thread 'main' panicked at 'assertion failed: `(left == right)`
  left: `[204, 204, 255, 255, ...]`
  right: `[204, 204, 255, 255, ...]`: Generated image did not match expected (basic_text_white_background)', test/main.rs:188:5

I don't see a visual difference between the images but https://online-image-comparison.com highlights the line under the sentence in black.

Thanks for the report, would it be possible to give some details about the OS and GPU you're running with please? Also could you please attach the _ACTUAL image which gets generated in test/assets/expected_images.
