--- Comment #4 from Guilherme Silva guih.rox@gmail.com --- I tried running git bisect, but as I'm not too familiar with the wine compiling process altogether, I was getting some errors while applying the staging patches in version 3.6 and I didn't know if I could safely ignore them or how to fix them. So instead, I downgraded the pre-compiled wine-staging package in Arch Linux and the last version which tray icons still worked is 3.5. Starting from version 3.6 it stops working. While testing version 3.5 and downwards I noticed that the system tray icon this black background, whilst in version 3.6 the background was transparent like it's supposed to be, but the functionality was gone.
