Dear all,
since 4.9-rc series started I see heavy redraw problems on i915. Starting or resizing for example the digikam window messes up completely the content.
I have seen this at least since rc2 (I often wait till rc2), and confirm that 4.8.0 does not exhibit these problems.
A screenshot of the redraw problems is attached.
