Package: kwin-x11 Version: 4:5.8.2-1+b1 Severity: important Dear Maintainer, with the nvidia driver (375.26-2) kwin sometimes starts flickering the screen contents, especially the content of semi-transparent windows starts flashing dark and bright until you stop compositing (shift-alt-f12 hotkey). I think this is a problem, which should be fixed in the stretch freeze before kwin is fit for a stable distribution.
