Please, include an application icon with better quality. The current image looks like 16x16 that causes very weird looks in different places. For example, it is how it looks in Alt+Tab panel:

And this is the tray panel: https://i.imgur.com/0hYV8zj.png

I made an alternative logo. I've already changed my system to use this one.

Also, if the project is interested, it's yours. You can credit me as Frithfolk.

Here's the icon in use. Looks sleek.

Expwez, in your screenshots, what operating system is that?  Is it Windows 10?

How do you get the ALT-TAB screen to look like that?  Mine does not have large icons like that, and it shows a thumbnail of the window.

Also, how do you make your tray notification area work like that?

Does anyone else know?

Exwez and myself are both using versions of Linux. His is "Manjaro" and mine (guest from above) is "Ubuntu Gnome". You could ask a friend to help you make a "Live USB" and you can try them out without affecting your system.

While they look quite striking, there are many differences between Windows and Linux so it's definitely best for you to try it before committing to change systems. Also, most of us Linux users keep a few copies of Windows in things called "Virtual Machines" so we can use Windows' software when we wish to. It's an interesting rabbit hole, I recommend you to have a go.

You're what we call the best kind of user! One that provides feedback and a completed solution :-)

This was fixed for version 2.78.  The alt-tab icon in Linux/GTK should look much better now.  The tray icon in Linux/GTK may still be low-quality in some contexts due to limitations of the GTK API.
