cygwin at-spi-bus-launcher and xwin-xdg-menu high cpu

Question

Running cygwin/X I see at-spi-bus-launcher and xwin-xdg-menu are using most of the cpu. There are two instances of xwin-xdg-menu.

Between the three of them there isn't much left for anything else. How can I fix this?

Answer 1

Solution:
Create a ~/.startxwinrc file, and add one line:

exec sleep infinity

Make ~/.startxwinrc executable by running chmod +x ~/.startxwinrc.

Reason I suspect this worked:
startxwin searches for a ~/.startxwinrc file to execute when launching. If startxwin does not find a ~/.startxwinrc file, startxwin will follow the default routine outlined in /etc/X11/xinit/startxwinrc.

The default routine launches /usr/bin/xwin-xdg-menu, somehow causing me to have two xwin-xdg-menu processes, one of them with very high cpu. Creating ~/.startxwinrc bypasses the default routine, disabling /usr/bin/xwin-xdg-menu from launching altogether.

exec sleep infinity keeps the x server alive after launching.

Answer 2

rm -r ~/.dbus*

Then start XWin

If it's still stuck, open task manager and see if there are 2 XWin.exe processes kill the one with lower memory usage
