Caught this in my server log and the client got disconnected:

client was running an xterm and gedit
#2487 closed as duplicate of this bug.
The line that causes the error is:
this.offscreen_canvas_ctx.drawImage(this.draw_canvas, sx, sy, sw, sh, sx+xdelta, sy+ydelta, sw, sh);
Two things to look into:
swap_buffers
must be called at least once before we can use scroll paint
(not seen it since)
