screen-cast: Fix window recording on HiDPI

Browse Source 
Using the same scale for the window as the
logical monitor only works correctly when having
the experimental 'scale-monitor-framebuffer'
feature enabled.
Without this experimental feature, the stream
will contain a black screen, where the actual
window only takes a small part of it.

Therefore, use a scale of 1 for the non-
experimental case.

Patch is based on commit 3fa6a92cc5.
