Trace view crashes when doing quick actions with huge trace data

[laksono]

Procedures:

1. Open a huge trace data
2. Zoom-in, zoom-out, move left, right, undo, redo in a very fast. Do this action multiple times in a second until it crash
3. Error message from GTK:

This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 5302692 error_code 141 request_code 138 (RENDER) minor_code 7)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
