Super slow greeter interface.

[rRobis]

So I have a problem. I'm using Antergos, and my webkit2-greeter is super slow(interface). When I type in something, it takes like 5 seconds to do that(response delay 5 seconds). The animations have delay. It's like it freezes periodically. The mouse is also slow.

I tried 2 themes and both of them are slow ( Material and Antergos default theme).

I have intel I3 procesor, Intel HD 3000 graphics card, single screen, 8GB of RAM. How do I fix this?

I have a workaround for my setup, using archlinux.

File: /etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
        Identifier  "Intel Graphics"
        Driver      "intel"
        Option      "DRI" "2"             # DRI3 is now default 
EndSection

The issue, for me, appeared when intel updated to DRI 3. This file is made from the instructions on the archlinux wiki.

This might help finding out where the issue lies.

This issue should be addressed by webkit2gtk 2.12.4 (which will be in arch repos soon)
