**REPORTED** Scroll wheel issues on Mac

Scrolling to select another item is somewhat broken for me since the last update when using an external mouse on my Mac. When I scroll slowly, I have to scroll like 5-7 notches before it goes to the next item. When I scroll fast, it skips like 5 items at once.

I recorded a video to illustrate the issue better:


I've found a Reddit thread about the same issue: https://www.reddit.com/r/Terraria/comments/gl6150 .

It seems to me that this could be related to smooth scrolling on the Magic Mouse, Magic Trackpad and built-in trackpad, because scrolling on the built-in trackpad works just fine.

We've been getting a few reports of this and are still looking into solutions. I know at least one reporter indicated that swapping out his mouse fixed it, so it may be a conflict between specific brands of mice.

The mouse I'm using is a Logitech G500s, I have also tested it with a cheap wireless Microsoft mouse (don't know exactly which one anymore). I'm curious as to why switching mice would help since the mouse works fine in other applications and games.

As I said, it may be a conflict between certain brands of mice with Terraria, hence why we'll need to look into it :)

I have done a lot of testing and I have narrowed down the issue to whatever version of SDL that Terraria uses. I replaced Terraria's SDL binary with a binary I built myself using the latest version of SDL (2.0.12) and this issue completely went away. There may be other side effects of upgrading the SDL version, but I haven't seen any problems yet.

For anyone who wants to apply this workaround:
  • Download libSDL2-2.0.0.dylib.gz.
  • If it doesn't automatically get unzipped, then unzip it.
  • Go into steam and right click Terraria in the Steam library.
  • Select properties.
  • Go to the local files tab.
  • Click browse local files.
  • Right click the Terraria application and select Show Package Contents.
  • Go into Contents > MacOS > osx.
  • Replace libSDL2-2.0.0.dylib with the one you downloaded.

@Silly511 Thanks a lot for the investigation, I'm going to document this in our ticket for the issue, will probably give us a lead!

@Silly511 I tried this and now Terraria won't even boot up. In the force quit option it says it isn't responding.
Edit: I tried the steps again and this time it won't even go that far, it boots up and immediately stops.

Thanks @Silly511, it mostly fixes the problem!
When I scroll a single notch at a time it goes to the next item. If I scroll a bit faster it still skips over items, this is less of an issue but not ideal.

I don't know why it doesn't work for you, it seems to work for everyone else. You can reverse the changes by going into steam, right-clicking Terraria, clicking properties, going to the local files tab, and clicking the verify integrity of game files button.
