Picture showing corruption

When an nedit window is scrolled the display becomes mangled. This happens with some other applications but otherwise system and display is fine. Attachment shows corruption.

Nedit is a simple text editor based on the Motif widget set.

Does not happen when the nedit window is at the top left of the first screen.

If I set (Option "ShadowPrimary" "on") this fixes the problem. This is the work around but I'm not sure if this will mess up performance or other things.

Hardware is older Dual Xeon with graphics board: [AMD/ATI] Oland PRO [Radeon R7 240/340]. Dual monitors in use on HDMI and DVI.

Software is Fedora23 with all updates to date. Uses radeon driver: xorg-x11-drv-ati-7.6.1-3.20160215gitd41fccc.fc23.x86_64, kernel: 4.5.7-200.fc23.x86_64.
GUI is KDE/Plasma with compositing enabled as per default.
