User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0
Steps to reproduce:
- Start Nightly (2019-07-17) with a new profile. WebRender is enabled by default.
- Open a web page with a text area or text input (e.g. https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_textarea)
- Start typing reasonably quickly in the said text area.
3'. Alternatively, hold a letter and release it after a couple of seconds.
3''. Alternatively, go to about:config and hold a letter in the search text box; stop from time to time and watch the results panel. The new preference name should be the same as the contents of the search box, however it flickers to a shorter length, then back.
Actual results:
Once every 10 seconds or so, the last typed letter (and possibly the cursor, too) disappears, then shows up again a short while later. When it's not glitching, the displayed text is correct. The effect is as if an old frame is redered instead of the current one.
Expected results:
No glitches while typing.

More details:
- I see this on Windows 10 1903. I'm not sure if it happens on older versions
- disabling WebRender fixes the issue
- opening Game Mode (Win-G) and using the screen recording functionality fixes the issue (while recording is running)
- I just realized that my graphics driver is ancient. I'll try to update it and re-test

The issue still occurs after upgrading to the latest Intel GPU drivers (26.20.100.6912). Also, it doesn't happen on Linux.

Thanks! This sounds like a duplicate of bug 1556634.

:darkspirit thanks, it looks like a duplicate indeed. I don't think it's Intel-only, as it also happens with my NVIDIA GPU.
