FWIW, I'm working on integrating https://github.com/linebender/piet-gpu (see the "compute" branch). It natively supports stroked paths, including polylines.

https://man.sr.ht/git.sr.ht/annotations.md is 404. It's linked from https://drewdevault.com/2019/07/08/Announcing-annotations-for-sourcehut.html.
FWIW, I'm debugging an issue where annotation uploads report a 405 Method not allowed. See the end of
https://builds.sr.ht/~eliasnaur/job/290129
However, I can't remember the content of my secret upload-annotations, nor why it succeeds in spite of a 405.

The emulator is Android 10; API 30; x86. The device is a Motorola Condor (Moto-e) with Android 7. Go version is 1.14.4 on Debian amd64.
On the emulator logs, I noticed complains about missing OpenGL support and "Unexpected CPU variant for X86 using defaults: x86". Note the capital "X". It also complained about missing instructions, probably because of the ISA mismatch:
Mismatch between dex2oat instruction set features to use (ISA: X86 Feature string: -ssse3,-sse4.1,-sse4.2,-avx,-avx2,-popcnt) and those from CPP defines (ISA: X86 Feature string: ssse3,-sse4.1,-sse4.2,-avx,-avx2,-popcnt) for the command line:
The SSE instruction family is used for vector processing, so I suspect that might be the reason why OpenGL is not working. The device version does not complain about OpenGL not working.
I don't think the device CPU and instruction set have any influence over OpenGL performance and features, since the GPU is a separate processor.
Logs attached. The emulator log is obnoxiously large, if your text editor can't open it, try emacs or 'cat log.txt | egrep "kitchen"'.
Thanks.
The important log message for the emulator is
org.gioui.kitchen: no support for OpenGL ES 3 nor EXT_sRGBwhich indicates that your emulator for some reason haven't enabled OpenGL ES 3. The emulator does support ES 3, so you probably need to tweak a configuration somewhere. I found
https://stackoverflow.com/questions/24874066/does-the-android-emulator-support-opengl-es-3-0I didn't find interesting log entries for the Moto E glitchy graphics, but given the GPU chip (Adreno 302) was announced in 2013 I'm not surprised graphics rendering doesn't work well. FWIW, Viktor Ogeman and myself are working towards a replacement renderer based on GPU compute which will be able to run on the CPU, side-stepping (buggy/slow) GPUs.

I have s similar problem for patches to ~eliasnaur/gio-patches. At least two mails appeared in my inbox but not on the mailing list: https://paste.sr.ht/~eliasnaur/4ef2a2a0ef4f62e25d9d94078dd2e2ebd25898f0 and https://paste.sr.ht/~eliasnaur/04be3a9d1c2a547934a977d57ddf6b8769689c4f .

The fix https://gioui.org/commit/e214191 should solve the problem. Re-open if not.

Interesting. Does the other examples (hello, kitchen) work on the same setup?

The reporter of https://todo.sr.ht/~eliasnaur/gio/157 included a link to the issue itself in a follow-up, resulting in a " referenced this from #157".

Please elaborate: Provide a small example of a program that doesn't behave as you expect.
It sounds like you need to use either op.InvalidateOp:
https://git.sr.ht/~eliasnaur/gio/tree/master/example/kitchen/kitchen.go#L158
or Window.Invalidate:
https://git.sr.ht/~eliasnaur/gio/tree/master/example/kitchen/kitchen.go#L149
depending on your situation.
