tomocafe I also have this issue with Google Play Music Desktop Player. The tray icon is huge compared to the others. 😕 Especially once you have a lot of icons from different apps in the tray, it starts to look really funky.
tomocafe algent Would love to use your icons, are they hosted anywhere? Ideally, though, this should be better it off the box....
algent Hexchat is easy, just copy the .png icons to $HOME/.config/hexchat/icons. I made some icons using inkscape and I uploaded them in github. Same with telegram. The icons should be placed to $HOME/.local/share/TelegramDesktop/tdata/ticons. You can find on github a lot icons for telegram. For telegram I have found a script to generate icons as much as you want. This is the script. About odrive. I have packaged it localy using my icons for tray.
