Previously had this issue:
Drag selection cursor jumps down right after 1709 16922 update.
After 1709 update, when trying to drag select files, cursor would jump to the screen end.

Now just updated to 1803, first thing wanted to check if this bug is fixed.
It is fixed, I can drag select without cursor jump, but while drag select, cursor would stuck with popping sound when I try to move my mouse/cursor.
Keyboard buttons doesn't respond as well, till I press "Start" on keyboard. 5 seconds later it would unfreeze.
When this issue occur "Desktop window manager" usage spikes CPU at 100%

*Sigh* Microsoft...
