Hi,
Attached is a patch which fixes an issue I have with laggy screen
updates when resizing or moving floating windows.
What the patch does is:
Limit the amount of updates when resizing or moving a floating window
to 60 times per second. This makes resizing and moving alot smoother
and by limiting it it also uses alot less resources.
Patch also available at:
http://www.codemadness.nl/downloads/patches/dwm/0001-limit-updates-per-second-for-win-move-resize.patch
Applies cleanly against latest git master
(18248ebf4b9465b837e717dcd14a5202a98248e0).
Kind regards,
Hiltjo Posthuma

Subject: [PATCH] limit updates per second for win move/resize
Limit the amount of updates when resizing or moving a window in floating
mode to 60 times per second. This makes resizing and moving alot smoother
and by limiting it it also uses alot less resources on my machine.
