uTorrent 3.4.3 currently in Rapps has several issues.
1st the SHA1 hash does not match giving a warning.
When you run it manually afterwards, the app immediately crashes.
In opposite to this uTorrent 1.8.5 r17414
is smaller, downloads, starts, runs and even downloads! fine.
No visual glitches even!
