Describe your issue

7TV animated emotes with transparent backgrounds have a trailing effect on v2.4.1 and v2.4.2 AppImages, issue is not present in v2.4.0
BTTV and Twitch animated emotes are unaffected, issue only with 7TV ones.

Below couple of examples with version 2.4.0, 2.4.1 and 2.4.2 from left to right respectively

Reminds me of the issue with 7TV animated PFP's SevenTV#69 (comment) - which turned out to be an issue with QT 5.12.12

I wonder if this is the same style of issue, but it presents differently, as we switched the appimage from QT 5.15.2 because of #4397

Can you try using the flathub version or the Ubuntu 22.04 .deb?
AppImage support is being phased out to a 'last resort' kind of distribution.

Tried with .deb package and no more trailing, hooray! :)
