I've got an application running on Ubuntu. Whenever it fails to respond to system events (because threads deadlocked, or busy-looping), the windows gets greyed out. I understand this is useful in most situations.
The thing is, quite often the reason it is unresponsive is that I'm currently debugging it in gdb, looking at matrices of numbers and callstack, inspecting variables, etc...
In those situations, I want to see what was rendered on the window as it contain useful information and especially nice colors and graphs. Once greyed out, all the blue, red, green, etc... information is converted into useless grey.
**Is there any system setting I can tweak so my unresponsive window doesn't get greyed out?** Just displaying whatever was rendered last is good. Is a huge multi-person project, so I can't change the overall architecture.
(please don't answer anything about keeping the app responsive. I'm in gdb, and it will take more than a second)
The window manager used is "whatever is the default". More preceisely, I guess it's Compiz, over Gnome:
wmctrl -m
