A DESCRIPTION OF THE PROBLEM :
I'm running jEdit (http://www.jedit.org/). After switching the monitor, I see that the jedit window is not painted anymore. In the console I see a stacktrace of ClassCastException in sun.java2d.xr.XRPMBlitLoops.
It seems that partial repaints are working, e.g. if I scroll the text pane, it is redrawn.

There is a workaround - disable the Xrender pipeline. Then there are no problems/exceptions after switching the output.




REGRESSION. Last worked in version 7u80

ADDITIONAL REGRESSION INFORMATION:
I didn't actually test it with java 7, but I don't remember having seen this. And as far as I figured out, the xrender pipeline was disabled by default in java7.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Start jEdit
2. Change display output: Switch the displays (turn the internal display off, turn the external monitor on). I doesn't happen in clone mode. E.g. using xrandr: xrandr --output eDP1 --auto --output DVI-1-0 --off



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The jEdit window doesn't change.
ACTUAL -
The jEdit window just shows a gray rectangle. No menu, no text pane.
