I'm trying to do animation with grid. Basically it's a vector field, like

Correct.
Any way to avoid this flash? Thanks.
There are a couple of ways, but unfortunately they may not be to your
taste ...
1) Use windows (where double-buffering has been implemented)
2) Find some way to convince someone to modify the X11 device (or
whichever device you are using) to support double-buffering
3) Provide a patch for the X11 device yourself ...
