步骤
你的系统

See if one app causes it
Open Task Manager (Ctrl+Shift+Esc). If Task Manager flickers too, it's likely the display driver; if it doesn't, an app is likely the cause.

Restart the graphics driver
Press Windows+Ctrl+Shift+B. The screen goes black briefly while the driver restarts.

Update the graphics driver
Get the latest driver from your GPU or laptop maker.

G-SYNC, FreeSync or Windows' variable refresh can flicker at low frame rates on some panels.
