While this issue happens, whole windows UI is unresponsive::
the mouse movement is completely delayed by multiple seconds, even without touching mouse, the cursor still performed the delayed movement by up to 15 seconds.
For example, when scrolling, the screen is unable to keep up with the mouse wheel, and it will keep scrolling for a while after I stop the mouse wheel
Keyboard input is delayed that much, that you can watch your letter by letter typing hands-free.
Windows task bar freezes, noticeable also the clock is freezes and windows systray time does no longer count up.

All unresponsiveness remains until quit vscode.

Meanwhile, the entire time CPU and ram usage was low.

The only Workaround is:
`c:/Windows/System32/taskkill.exe /F /T /IM "Code.exe"`
or
`c:/Windows/System32/taskkill.exe /F /T /IM "Code Insiders.exe"`
