Just checked, can confirm this is also an issue here.
CPU use jumped from 2% up to around 8-10% just by hovering over the headlines for the tooltip to come up.
Hello @DanMan, @LiamDawe, are either of you still experiencing this issue on an up to date system?
Nope, all good.
I still get this on the forums for example. If I click on a forum thread, on the right side there's the "more discussions" area. If I hover over those, the tooltip still makes the client freeze for a few seconds.
Sysinfo (only slightly outdated), using Steam Beta from today.
Thanks for rechecking, you've described the issue being tracked at #3994. I'd prefer that we use the older issue report to focus on that specific symptom. Are you seeing similar symptoms elsewhere?
Wherever those tooltip are used, basically. Since the news section has been completely overhauled, that one's off the table. But I guess you're right that it's the same issue.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
The CPU usage skyrockets to the point that the whole client freezes for a few seconds and my CPU fan speeds up. It's not just that page (see below), it happens wherever those tooltips show up. Like also with those links to the right of every community discussion thread. This started happening with the new library. GPU acceleration on/off doesn't really make a difference. Doesn't happen with my desktop browser, only through the Steam client.
I posted it on the Steam Beta Forum, but either I'm the only one or nobody's reading those.
