On 17.3 core, I noticed that, unlike Xorg (which Nvidia 580 broke for me), Wayland has a hair trigger for deciding that an application is not responding (and makes the "Wait" and "Force Quit" dialogs appear constantly when a game is simply loading a new scene/menu).
Is there a configuration option to make it more patient (a longer timeout maybe)? I'd even take disabling that dialog with how incessantly it pops up.
