I am sorry you are having problems with the driver but let me help you.
Please note that we have released a new driver version 3412. Please uninstall the current driver and download/install the latest one here:
I have tested a DZ87KLT-75K motherboard with the Intel® Core i7-4770K (HD 4600) and I was not able to replicate the bugs you mention.
My best recommendation is to update the graphics driver and update the BIOS in your system provided by the computer manufacture.
