meanwhile i have solved this problem by using the free radeon driver
(xubuntu 14.4, with xenial kernel), and writing a minimal xorg.conf
Identifier "radeon whatever the cards name is"
Option "AccelMethod" "glamor"
Option "ShadowPrimary" "on"
Option "DRI" "3"
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
