If your error is consistent I'd suggest to check

glutin/glutin/src/api/glx/surface.rs

Line 222 in b92fb63

super::last_glx_error(self.display.inner.raw)

before calling swap_buffers as well. The error may bubble up from some other place?

Hi @kchibisov will be fixed by #1475

the example is OK now
