[SOLVED] Keyboard lag after system resolution change

[cubicap]

Hello,
I am experiencing a weird problem on Windows 10.
Anytime resolution of my laptop screen changes keyboard does not work as expected. After this event, there is huge input lag on it. It takes sometimes even a few seconds to "write" the character pressed. Even though it seems the keys are saved to some buffer because when I type a few characters, they are slowly appearing on the screen.
The problem persists after the resolution changes back to default.
To get rid of this problem I have to reboot the computer.

I have tried to clean install the computer - short after the process, everything worked fine but two weeks later it is back again.

To add, in Event viewer I have a flood of WHEA-Logger warnings which seem to be related to PCI Express Root Port in which is connected Qualcomm Atheros QCA9377 Wireless Network adapter. (EDIT: seems not to be related)

Thanks for any advice.

How much RAM? 32 or 64 bit Windows? Maybe you need to add RAM.

Sorry, forgot to mention.
Windows is 64 bit.
I have 8 GB RAM so I think it's enough.
I've got Intel HD 520 and NVIDIA GeForce 940M.
Processor is Intel Core i5-6200U.

8 GB ought to be enough, I agree. You must have something that's making Windows go through error recovery. Try using the Event Viewer to look at the cryptic System log for entries flagged ERROR to see if you can find clues to what the culprit is.

I have tried to find something in the Event Viewer but without success.
Anyway, I have found this post with a similar issue and disabling SuperF4 seems to have solved the problem.
