1.1.8 causes massive slowdown in opening new Alacritty windows #47

Open Hubro opened 2 years ago

Hubro commented 2 years ago

The egl-wayland upgrade from 1.1.7 to 1.1.8 was identified to be the cause of the massive slowdown in opening new Alacritty windows here:

https://github.com/alacritty/alacritty/issues/5608

The verbose logs are provided in that bug report.

The relevant line is:

[2021-11-14 12:51:44.031082609] [INFO ] [alacritty] Device pixel ratio: 1

Everything appears to freeze for 3-5 seconds right before this line.

I'm not sure how I can gather more information for troubleshooting, so please advise.

I would just like to confirm, as one of the other posters in that issue, that downgrading egl-wayland to 1.1.7 also fixed the issue for me.

Other info: I have Intel graphics, not Nvidia.

I think this is similar to an issue affecting QtQuick. Version 1.1.8 is likely interacting badly with this snippet of code from the Smithay client tool-kit https://github.com/Smithay/client-toolkit/blob/817ebb4c74dee7985411820e9c90fd09ea3e1027/src/event_loop.rs#L87

I too am having the same issue, both with Alacritty and Wezterm on GNOME 41.2 Wayland

It’s fixed by https://github.com/Smithay/client-toolkit/pull/214. Thanks to the great people! 🎉

The issue still exists on Alacritty and it uses the updated version of smithay/client-toolkit.
