Native Wayland windows flicker between positions on focus change

[Araly]

(1) Issue/Bug Description:

In tiling mode, when I change the focus from a window to another, all the Wayland windows will flicker between their assigned position in the tile, then an older position they had, then to the correct position again. It happens in maybe half a second.

It only affects native Wayland windows, not XWayland windows. So for example, my browser Vivaldi is not using native Wayland yet, and is not affected. The same way, kitty (in X mode), Discord, Steam are not affected. Gnome Files, Tweaks, Extensions, Gnome Settings, kitty (in Wayland mode) are affected.

I don't have this issue when I launch Gnome in X mode, or in floating mode.

Additionally, when native Wayland apps open pop up windows (which Gnome does a lot), the whole app flickers. And when I close the pop-up, the whole app flickers again.

(2) Steps to reproduce (if you know):

• install Gnome and Pop Shell extension
• run Gnome in Wayland mode
• turn on tiling mode
• open up a variety of x and wayland windows
• move them around in the grid maybe, so they have older positions to flicker too (although it seems like just them appearing is a position, and then being tiled becomes the new position)
• change focus from window to window, either with key bindings or with the mouse

(3) Expected behavior:

When I change focus from a window to a window, all Wayland windows behave like the X windows, and stay in place where they are.

(10) Other Notes:

Here's screenshots of windows flickering

These are the example of Gnome Settings flickering when I move my mouse (which grabs focus on hover) from Vivaldi to Gnome Settings. (mouse on Vivaldi → mouse on Gnome Settings, which changes position → Gnome Settings settles down in the tiled position)

Then here's a Gnome Settings when I click on a button that opens a popup, flickers, then I close the popup and it flickers again

I'm experiencing the same issue. There seems to be that moving windows around, and opening and closing new ones changes which which window will flicker, sometimes its all flickering and sometimes none. I was testing with all windows being Wayland windows.

As discussed in #1330, the temporary solution is to downgrade mutter. On Fedora:

sudo dnf install mutter-41.0-4.fc35

And then restart

[vincentDcmps]

do you know if this bug will be fix on next mutter release in archlinux if I downgrade mutter to 41.1 gnome doesn't work anymore same thing if I install 42 alpha

[Araly]

yeah I prefer to live with the bug or Xorg for a while rather than mess up Arch's package versioning for Gnome. Hopefully it will reach master/main on its own without anything needed from users

[ryleu]

confirmed on fedora 35, with both integrated intel and integrated amd graphics, so it seems to be GPU-agnostic

also confirmed on artix, though that was fetched from bedrock poki, but the results should be the same

[Araly]

I don't seem to have this issue anymore, on Arch. Hopefully it can reach Fedora soon too

[gitkeerthi]

I'm experience this issue. Using intel + wayland only (nvidia is not installed)
