I have a flickering problem with my Intel i7-4702MQ (Iris HD 4600) under Windows 8.1. Especially visible on dark areas, e.g. if a desktop application is using a dark theme. Normally people report flickering issues of games but this one is related to the Windows desktop. There is no way to alter the frequency in Intel settings dialog, only one option is available (60p Hz).
Is this a known issue of this driver version?
I know here are some users with exact the same problem but thats mostly older threads.
