Hi,
I sometimes catch high-CPU usage in GWorkspace. It doesn't go away by
itself, I need to restart the application. The application remains
functional, it does not "hang".
I don't know how to trigger it except having it run for hours or days...
It could be related to checking many images or to having file system
changes while open, I don't konw. I just though checking it after
reading Patrick's issue.
Since it is hard to reproduce, I just let it run in gdb for days and
eventually hit ctrl-c when I heard my fan spinning and htop showed CPU
(amazing how a multi-CPU sytem can hide such issue).
I hoped to see something, but without a proper hang, I guess it is more
like poking in a haystack.
Stacktrace is below. I see it is pure GNUstep.
I guess this is just the application runloop waiting for mouse or
keyboard input?
