As a reply to @Ragmaanir in 'Incorrect scolling behavior in Linux client. #4644':

for me this scrolling behavior is everywhere (store, community, library/tools, friends list). The store is just the most annoying and important part. I dont know, but i guess the issue is more general than the store-page issue and that there is/might be a general solution.

Indeed, it happens all over the place.

An interesting(?) thing I noticed, is that Steam seems to ignore the user settings in the Windows build as well, while running it via Wine. To be a bit more specific, for me the Windows build scrolls about four (4) lines, while the Linux build scrolls about nine (9) lines (tested on the hardware & software survey section).

I can set the scrolling to 0 lines, and I get no scrolling in, for example, the Falkon web-browser, but Steam still does what it does.

Tested on Gentoo Linux mainly with LXQt, and somewhat with Xfce4.

According to a friend of mine, it's a little bit funky in a native Windows environment as well, where having the Windows setting at 2 lines will scroll 4 lines, and 3 will scroll 9 lines.

This is another QOL fix that's badly needed.

Is there any new on this topic? The issue has been opened since Nov 25, 2016, and is a huge annoyance when browsing anything related to the steam client. I'm actually going out of my way not to use the client as much as possible since the scrolling is so horrendous.

@gdrewb-valve This is still an issue, any progress on this?
