As additional information, the Intel® HD Graphics 4000 controller is not compatible with Windows* 10, there are no drivers available for that Operating System, so any kind of inconsistencies will be expected when using both of them.
Intel Customer Support Technician
As was indicated, there is never been any Windows 10 support - read: no drivers from Intel - for Intel HD Graphics 4000-based processors. Microsoft provides compatibility drivers that allows these older, unsupported PCs to be used with Windows 10. These drivers are typically from an older version of Windows (Windows 7, 8 or 8.1) and they were forward-ported to Windows 10 driver models. Now, while MS provides these compatibility drivers, they do not accept responsibility for them, they will not respond to complaints about them and they definitely do not provide maintenance resources to support them. If something goes wrong, there is no recourse.
Bottom line, if a problem has developed, no changes were made to the driver, so any problems that develop are as a result of whatever other software you have installed. Your best recourse, if this is a PC and can accept it, is to install an add-in graphics card. If you cannot do this, you may want to reinstall Windows 10 (which, just saying, I believe you should be doing once a year for optimal performance anyway).
Sucks, but this is the reality of the situation,
