Is there a way to disable the white brackets that are placed on each corner of a window when captured?
Yeah, wait for 1.1, this is a bug. We try to cut the corners but didn't check what window type the window is.
I want to upload an "unstable" tomorrow.
Can you have a look at our 1.1? It's still in development, might have some other issues, but the first download is available and so far we have little reports of bugs.
