Bug#847553: epiphany-browser: display not updated (after some random time)

[Jérémy Lal]

Package: epiphany-browser
Version: 3.22.3-1
Severity: important

On about any web site, the page display stops being updated
from time to time (several times a day here):
- the mouse pointer still changes on hover
- if i click on an anchor on a single page website,
url changes but display is still the same
- scroll does not work at all
- title bar is still somewhat working, but doing things there does not update display
- reloading the page hangs
- cpu is idling
- window is difficult to close (might close after some time)

This bug appeared a few days ago, after a direct or indirect dependency
update, but i have yet to find which one. libx11, mesa ?
