chromium right click
With DRI3 set as default in radeon driver, screen corruption appears in plasma
taskmanager, system tray widgets and firefox&chromium right click menus.
DRI3 with glamour doesn't have this corruption, only EXA and XAA.
Corruption also happens if desktop effect are disabled in Kwin.
With DRI2 enabled, rendering is bug free.
This is rather old laptop graphics VGA compatible controller: Advanced Micro
Devices, Inc. [AMD/ATI] RV530/M56-P [Mobility Radeon X1600].
Using glamour is not an option since it is slower and results in higher
graphics card temperatures.
Kernel is 4.5, Xorg-server 1.18.3, gentoo linux.</pre>
