Your system has hybrid graphics; please tell me did you build the computer or it is pre-build?
If you have the second case, make sure you have the latest BIOS and drivers from your system manufacturer.
In the case of custom build, let me know motherboard model, processor model and memory specs.
Thanks for your answer. My system is pre-build. Is a Toshiba Satellite P50-B-11V.
I've all the latest drivers and BIOS.
Intel HD 4600 Graphics driver version: 22.214.171.12460
AMD Radeon R9 M265X driver version: 15.201.1101.0
Try to set Windows Scalling to 100%, you probably have now something like 125%
Brilliant! Indeed solved the problem..that never crossed my mind.
