Created attachment 8807554 [details] lines on firefox with pen.mp4 [Affected versions]: - Nightly 52.0a1 [Affected platforms]: - Windows 10 x64 [Steps to reproduce]: Make sure that the build has e10s enabled and the pref "browser.tabs.remote.force-enable" set to "true". 1. Go to about:config and set the "dom.w3c_pointer_events.enabled" preff to "true" 2. Go to www.addtext.com 3. Tap on the "Restore down / maximize" button next to the "X" / "Close" one with a stylus. [Expected result]: - The window is minimized or maximized accordingly. [Actual result]: - The window is minimized / maximized but there are black lines thrown to the Firefox window. [Regression range]: - This is not a regression since this is a new feature. [Additional notes]: - This issue is not reproducible by mouse or touch, only by stylus and only with Pointer Events preffed on. - Please see the URL section for a detailed screenshot of the issue.

The easier way to reproduce this problem is dragging the Window with pen after drawing something (with pen) on the Window. The pen path will be redrawn when the window is invalidated.

Is it something we should uplift to 52? I have difficulty to see the impact
It only happens when users turn on pointer event preference and operate FF with a stylus on Windows. After drawing something on FF with the stylus and trigger window to be repainted (ex. drag the window, maximize, or minimize the window), the drawn lines will be shown on FF (then disappeared)
