Mouse buttons don't work with keyboard/d-pad at the same time

Hello!
Just received my GPD Win and immediately noticed a problem that mouse buttons stop working when you press D-pad or keyboard buttons.
I was able to google up a Reddit thread with similar problem, but with no fix what so ever: https://www.reddit.com/r/gpdwin/comments/5gyup1/left_mouse_button_wont_work_when_dpad_is_triggered/

This is a very serious design flaw – I really hope there is some driver fix or anything.
Probably not the first guy asking about this problem so please help – most games are literally unplayable because of this issue.

I'm completely pissed off about this problem, even have thoughts on selling GPD Win because of it – who needs a Windows gaming machine where you can't run forward and fire at the same time?
I know there are gamepad modes, but I don't need any.
If that's a Windows machine – it absolutely, without questions have to support classical mouse and keyboard input without absolutely no issues.

Figured out the problem thanks to people on Reddit, it turned to be one of Win10's hidden "features".
Here's a tread with the solution for those who will come after me: https://www.reddit.com/r/gpdwin/comments/73pcc5/mouse_buttons_not_working_with_keyboarddpad_at/

I didn't understand your question，Switch to the handle mode, the mouse will not move.
