visual bug: sometimes jump arrow lines are drawn strangely on hover

[zeebo]

Before hover:

After hover:

Notice the vertical line being drawn that wasn't drawn before coming out of the JMP 0x514b2e instruction.

Which backend is it using? Wayland/X11; Non-Compute/Compute?

[zeebo]

X11, and I don't know what non-compute/compute means.

@zeebo so there are two backends -- roughly https://github.com/gioui/gio/blob/b4acc239cd5b4b54787531409de8a7d2dd18c75b/gpu/gpu.go#L313

One using regular GPU primitives, the other using GPU Compute capabilities.
