I can confirm the issue occurs here for the combo box in my TF2 stats page.
Closed as duplicate.
This is a problem in Chromium and so can affect any web page with a combobox. It's the same thing as #194, just manifested in a different way. We put a workaround into the age verification page but we'll need to do the same thing on all other pages.
can also confirm for me - L4D2 Stats, Leaderboards page
We will be fixing pages as we encounter them, so these should clear up over time.
Just to add to what happens (For me anyway on TF2 achievements):
The Steam client uses 10% of my CPU (instead of the 0%-1% CPU usage) when I am mousing over the achievements dropdown, the RAM usage stays the same. The blue box that covers the option does not follow the mouse. When I click out of the achievements dropdown by clicking beside the box or clicking on an item in the dropdown (It goes to the correct page if that is done) the blue box goes to the correct place.
I use Lubuntu and have over 3.65GB of RAM spare out of 4GB (The steam client using about 180MB of that).
This problem is fixed, can be closed as resolved.
