After upgrading lib32-libx11 to 1.8.3-1 from 1.8.2-2, there's a whole lot of messages in /var/log/messages from the steam client which makes it really slow.

Steps for reproducing this issue:

1. upgrade library lib32-libx11 to 1.8.3-1
2. start steam
3. monitor /var/log/messages (or /var/log/messages.log) for new messages, possibly via tail -f. There will be a flood of messages like:

Note 1: not sure if this is a bug in the library itself, in plasmashell (most likely) or Steam.

Note 2: this bug is also described in this reddit post -- https://www.reddit.com/r/linux_gaming/comments/10459tz/steam_on_terminal_is_spamming_this_type_of_message/

Note 3: confirmed with 2 other friends which also use Arch Linux with KDE.

Note 4: downgrading back to 1.8.2-2 solves the issue.
