keyboard is incompatible with PPSSPP, it stop working sometimes.

[a5680737]

when i use PPSSPP with my keyboard connected, PPSSPP will remember my last command and repeat it for few seconds, and PPSSPP and keyboard is out of control meanwhile, no matter the command is from my keyboard or joystick or mouse. this issue happens once per minute maybe. really disgusting.
even more, with PPSSPP running, the keyboard won't work when i do other stuff with the keyboard sometimes.
when i release my keyboard, everything was good, but it feels bad i must pull out my keyboard everytime i want to play with PPSSPP
wondering if anyone met this before? how to cope with this?

btw, my keyboard is mechanical, and it has some media control function and light effect, i think this issue has something to do with the keyboard driver.

big thx.
