New tab content repeated 4 times as tiled wallpaper

This was previously reported as a Gnome Epiphany bug: https://bugzilla.gnome.org/show_bug.cgi?id=777291

I have a dual monitor setup. My laptop has a HiDPI monitor (3200x1800) and I use an external 24" monitor (1920x1200). I'm running an up-to-date Archlinux, Gnome 3.22.2 (with Wayland) and Epiphany 3.22.4 (WebKitGtk version 2.14.2). When I open Epiphany, any tabs that were open in the previous session open normally. When I click the new tab button or press CTRL+T, the new tab content is repeated 4 times like the attached screenshot. If I navigate using the newly opened tab, all page visits are broken like that. If I close Epiphany completely and reopen it, all tabs are displayed correctly.

Steps to reproduce:
1. Open Epiphany on Wayland.
2. Open a new tab.

Actual:
1. The new tab content is displayed 4 times as if it's tiled (see screenshot).

Expected:
1. The new tab content should display once covering the full window size.

Additional Info:
1. This happens only the first time I connect the external monitor. If I disconnect and reconnect the monitor. Epiphany works fine.
2. The same bug appears in the developer tools (when using "Inspect element").

I am trying to figure out whether this bug is still relevant.

Here I have a HiDPI laptop screen myself, but I cannot reproduce
this issue anymore when I plug a screen (I tried both a normal FHD
monitor and a HiDPI QFHD one).

Currently I am using GNOME 3.28, more precisely:

  - WebKitGTK+ 2.20.3
  - Epiphany 3.28.3.1
  - GNOME Shell 3.28.2

Theodoros, could you check whether this is solved for you using
newer versions of the software as well? Thanks in advance for
your time!

Hi Adrian,

I completely forgot about this. Indeed it's been resolved in the current Gnome/Epiphany version. I don't recall seeing this issue since 3.26, or 3.24 even.

Thanks!
