I usually have three or four Epiphany windows running with 10-15 tabs. I'm currently running:
Version : 3.8.1 Release : 163.3 Architecture: x86_64
Whenever I switch focus to another app and then back, or whenever I change tabs within Epiphany, the newly-focused page blanks completely, sometimes for over a minute. This seems to be independent of actually updating the page contents, just a repainting of the page as it was at the last refresh.
Has anyone else seen this behaviour? Is it an upstream issue?
