Stutter/hangups from displaying dynamic message

[hecrj]

I have noticed this myself too. The issue seems to trigger whenever we allocate a staging buffer to reupload vertices here:

wgpu_glyph/src/pipeline.rs

Lines 146 to 149 in 91249b8

	let instance_buffer = device.create_buffer_with_data(
	instances.as_bytes(),
	wgpu::BufferUsage::COPY_SRC,
	);

There is an issue open in wgpu that I think may be related: gfx-rs/wgpu-rs#261. As mentioned there, downgrading gfx-memory to 0.1.1 seems to fix the issue.

I think it may be a good idea to come up with an SSCCE that reproduces the issue with only wgpu as a dependency and report it there.

Oh k, yeah that's definitely an allocator issue, thanks. I think you could fix this by persisting the staging buffer : p
