Resizing window before changing active framegraph results in skewed rendered screen.

To reproduce, open attached example. Screenshots are included to illustrate.

Step 1) open program
Step 2) resize window
Step 3) switch to second framegraph
Step 4) resize window again
Step 5) switch to first framegraph (bug occurs, rendered screen is skewed)
Step 6) resize window, back to expected behaviour.

Also a problem in commit 5c5e807018cff0f807ce850da50a14e693c4365b (Aug. 8).
