log with errors

Opening external screen in grandma2 onpc application causes screen flickering
and a lot of errors like err:d3d:context_reacquire Acquired context 0x1846e840
instead of 0x88760

I have tested wine 2.13 - 2.17 including staging and all behaves same way. I
also tested it on integrated intel gpu (i915 driver) and on nvidia card (940MX
with nvidia driver)

To reproduce this issue it is enough to click Extern 1 or Screen 2 button to
open external window.
