Description of issue
I've been experiencing this problem from months now. What really draws my attention is that it continues to happen in recent builds, as it seems like such a basic and common feature.
Result:
_ The current layout in use is completely broken, staying in the Image Editor with a blank canvas showing the grid. The actual image is rendered and stored in the 'Render Result' slot, but is not set as the current image in use.
_ The new window is actually created, but totally blank, with no user interface and no rendered image.
_ Even worse, if you launch the render manually from the User Interface, it makes Blender to crash. Instead of pressing F12, just go to Render > Render Image: It crashes.
Before Blender crashes with a segmentation fault, this error occurs:
And when Blender closes it generates the log:

Does this happen with factory settings, or is there something specific in your preferences or you startup file affecting this?
You're right. It seems that something was corrupt somehow. By returning all to factory settings it works normally.
I investigated a bit further and discovered that this happens when the operator of
RENDER_OT_render
receives a copy of the current context as an override.Like this:
Then, all above symptoms replicate. It only occurs when the display mode is in New Window. With all other display modes, passing the override to the operator works just fine.

I can confirm that the UI gets into a weird state when running:
bpy.ops.render.render(bpy.context.copy(), "INVOKE_DEFAULT")
I also get a crash if I close the empty render window that pops up:
@brecht who to assign this to?
No one, this is low priority.
Can we fix this now? Blender is more stable and the new versions of my addons still have to deal with this unsolved issue.

I believe this seems to be related to this bug:
with an screencast add-on enabled, I get:
spam in the Linux console, it prints the line in a tight loop (~ 100% CPU load) until I stop the add-on.

Changed status from 'Confirmed' to: 'Resolved'
I'm getting this in 4.1. To fix it I have to maximise and then minimise any of the editors.
