When using Chromium, and there's 2 or more windows open, an intermittent hardware glitch is triggered, as if the screen was divided into a small quadrant grid, and these quadrants were horizontally and vertically skewed & degraded into particles.
The glitch happens in a 1/4-second, at random intervals between events.
OS: Ubuntu 18.04 / elementaryOS 5.1.3
Processor: Intel i5 540M (ThinkPad laptop)
Video: NVidia NVS 3100M (using proprietary driver 340.108)
Chromium version: 80.0.3987.163 (Build oficial) Built on Ubuntu
It only happens in Chromium or Chrome, since version 70+.
Firefox does not exhibit this behavior.
Logging out from the user session and logging back in and reopening Chromium/Chrome makes the triggered glitch disappear.
