Steam app laggy?

Perfectly working on my PC.

Yup, activating keys also. IIRC same problem was few months ago for people with big libraries, probably same crap came again with last update.

Yep.

yep

yes, it has been like that for a few days now.

Same for me.

Yeah, after the last update it's really slow for me on 2 different computers.

Yup :(

Same here =.=''

beta ?

It's happen in beta before this, and it maybe still didn't fix.

It can be tested by just hover "Library" tab after adding a new game (or idling a long time).

Yes. Since the last stable update. And Ctrl-F not working half the times.

It's happening to me all the time. For a year.
Oh, and sometimes Steam just crashes while I'm playing a game, which makes some games crash as well. Just brilliant.

Same here. After activating keys Steam hogs up one core and hangs for 20-30 seconds.

yes, scrolling the library takes up the processing power of one whole cpu core and feels very laggy

Yeah, it either lags a lot while switching tabs, or it fails to load the content.
But you have to remember, that Steam client is based on Chromium, so it has the exact same problems.

Activating keys is slow. It was like that awhile back too.

New beta seems to have fixed it. Just activated two keys and the client wasn't freezing.

I had lags before the latest update. Now it is fine.

Yep

Same for me; it became laggy after the last update. Just opening the Library lags it.

Same here
