[SWAY] Zed window flashes rapidly on Sway/wlroots

[gabvigano]

Summary

When launching Zed under Sway the window flashes rapidly. It works fine on Plasma Wayland.

Description

I recently updated Sway, Vulkan and Zed. It was working fine until I suspended my system with 'systemctl suspend'. When I resumed, Zed's window started flashing. The issue persisted after reboot. I tried to downgrade Zed to 0.189.5 but it didn't solve the problem. I then downgraded Sway to 1.10.1 and now it works again.

Steps to reproduce:

1. Boot Arch.
2. Update Sway/wlroots to latest version.
3. Suspend ('systemctl suspend') and resume.
4. Launch Zed.
5. Observe flashing UI.

Expected Behavior:
Zed should open normally and be readable with a steady display.
Actual Behavior:
Zed's window flashes very quickly and it is unusable.

Same issue here with sway in wayland. Forcing Xwayland solves it.

Same here. Installed Arch packages extra/sway 1:1.11-1 + extra/wlroots0.18 0.18.2-1 and rebooted, then Zed started flickering. I also have an Intel GPU, but a different one.

Suspend doesn't seem to be related to the issue. I haven't suspended the system recently.
