Viewport jumps really far in Linux version

[Emperor Jake]

When I right click scroll in the Linux version (both self compiled and generic binaries, any recent version) and I am running a large game, the game will lag for about half a second, and my viewport jumps to somewhere on the other end of the map. This is very annoying, could it please be fixed? (and the left click scrolling naturally causes accidental clicks on stations and vehicles)
This is not evident in the Windows binaries running in Windows or under WINE (which for the record also has drastically reduced performance with larger games)
