what is the global gui refresh metro ? and do other graphics cards have different options besides ShadowPrimary that allows fast access to pixel data? Can look it up but seeing that you have recently been dabbling in it...

Starting with an empty patch placing and dragging objects is very laggy.
Does somebody have the same problem or a fix for this?
i had similar problems with various versions of pd on various linux-versions, with the free radeon driver.
meanwhile i have solved this problem by using the free radeon driver (xubuntu 14.4, with xenial kernel), and writing a minimal xorg.conf containing
Section "Device" Identifier "radeon whatever the cards name is" Driver "radeon" Option "AccelMethod" "glamor" Option "ShadowPrimary" "on" Option "DRI" "3"
EndSection
the important option was ShadowPrimary (which needs glamor though). this option enables "fast cpu access to pixel data". maybe there is a similar option hidden in the settings (directx?...) for other graphicscards on other os too...
...after having added a global "gui refresh metro" to minimize updates of moving sliders etc. to my patches, everything works now (again) fine without that...
