[PATCH 0/1] MR1411: dwmapi: Fallback to 60Hz if the display frequency is invalid in get_display_frequency().

[Zhiyi Zhang (＠zhiyi)]

DwmGetCompositionTimingInfo() may throw a zero division exception if the display reports a 0Hz
frequency, which can happen when testing under Xephyr without -fakescreenfps option.
