[FFmpeg-user] Suddenly changing mouse sensitivity in dota 2 with opengl api on Arch Linux /Debian Linux after launching stream/record via ffmpeg with vaapi encoder

[KoreanFanOfficial]

Launch Dota 2 with opengl api. After launch stream/record via ffmpeg with
vaapi encoder mouse sensitivity suddenly changing without user prompt. When
you alt tab and recheck mouse sensitivity settings in terminal via xinput
list-props id , they shown sames as before, but mouse sensitivity is
different. So i use xinput set-prop id .. for changing mouse sensitivity to
previous (was before launching stream/record via ffmpeg with vaapi) value ,
but again after alt tabbing to dota 2 main menu, a few seconds later mouse
sensitivity changing again. With software encoder there were no issue. How
i can fix this?
