In tabbed layout, multiple browser windows slow each other down.

[crocket]

• Sway Version: 392d480

• Debug Log: sway.log

• Configuration File: config.minimal.txt

• Description:

• Enter tabbed layout.
• Open brave browser.
• Open a new window with Ctrl+N
• Switch focus between brave windows
• Open a URL in a new window. Go back to the first window. You see that there is a lot of lag in rendering of brave windows.

Can you provide a WAYLAND_DEBUG=1 log of your client?

WAYLAND_DEBUG=1 your-client >client.log 2>&1
# Then reproduce the bug

This is likely a client bug.

Eh, seems like it's using X11. I don't see anything to be done here...

[crocket]

This doesn't happen on i3.

[crocket]

I can reproduce this issue on qutebrowser, too.

[Emantor]

Since this happens on X11 this may be related to Xwayland, can you try to reproduce this within Weston?

[crocket]

@Emantor This is only reproducible in tabbed layout. It is not reproducible in split layouts. Weston is not a tiling window manager.

This issue is reproducible on qutebrowser which is a Qt program when Qt backend is XCB. When Qt backend is wayland, this issue doesn't occur on qutebrowser.

[crocket]

I couldn't reproduce the issue in weston-launch. This issue is reproducible in tabbed layout.

[fourstepper]

This is kind of happening on GNOME as well - if I open two Chrome/Chromium/Brave windows and full screen them, there seems to be noticeable lag to either of the windows - just saying that this is quite probably an issue with XWayland and not Sway itself

[Me7426]

Same problem at Chrome(xwayland) since version 85.

Same problem at Chrome(xwayland) since version 85.

I try to use Chrome-ozone(wayland) to avoid this issue, but it can't support IME, so sad...

[fourstepper]

@Me7426 what is IME?

[Me7426]

@Me7426 what is IME?

Input Method :)
All of Chrome/Chromium with wayland patch can't support input method, I don't know why.
