Ignore dpms status in Display::outputsIntersecting()

Vlad Zahorodnii requested to merge work/ignore-dpms-status-in-outputs-intersecting into master

Display::outputsIntersecting() is used to compute the list of outputs where the given surface is. The problem is that it accounts for the dpms mode.

This means that if an output is turned off, clients will receive a leave event and they may potentially decide to change the buffer scale and commit new buffers.

The dpms check was introduced to fix a crash, however since then, output bits in kwin have changed drastically, in particular how wl_output objects are destroyed. So, it should be safe to remove the dpms check.
