One reason is that fvwm does a lot of things during window motion.
You can speed this up by not using some of the functionality:
- Turn off SnapGrid and SnapAttraction
- Use simple window decorations without gradients or pixmaps
- Use only one page per desk (DesktopSize 1x1)
Another reason can be backing storage and saving window contents
obscured by other windows. If both are turned off, X has to do a
lot of extra drawing, but it actually depends on the video card
(and the applications) if the additional drawing is faster or
slower than caching the contents (because reading from the video
card is usually much slower than writing to it). Try if either
Style * BackingStore, SaveUnder
or
Style * BackingStoreOff, SaveUnderOff
helps.
