[linux] system tray icon cannot be smaller than a fixed size at 32x32 pixels

[dreamcat4]

This is an issue on some linux system trays because the SQRL icon is imposing a limit on the size of the task bar. Which in turn impinges on the title bar of windows and break the desktop layout.

This is especially true when the Desktop System Tray is configured to use 24px or 16px icon sizes... which are both smaller than 32px.

Looking at your code here it would appear that the system tray icon that sqirrel client is using is this one:

However it might be a better idea would be to instead use the SVG icon. For example:

https://github.com/sqrldev/SQRLDotNetClient/blob/master/SQRLDotNetClientUI/Assets/SQRL_icon_normal.svg

Which then will permit the desktop environment to do its own scaling of the icon properly. And without introducing any bitmap artefacting. This is expecially true when dealing with these smaller icon sizes.

Not sure how you create this system tray icon in your DotNet code. If it is in turn calling out to QT5 or GTK2 library. However I believe it should be possible to rectify this.

Looked at this is, it is currently not possible due to several limitations. Wont fix for now.

We have another report for this in the forums at https://sqrl.grc.com/threads/linux-testing-feedback.1109/post-9577, this time with a screenshot, I thought I would re-post it here just for future reference:

@josegomez, I guess the "limitations" you are taking about are due to us relying on third party code for the tray icon. Maybe we should think about writing our own notification icon implementation for Linux somewhere down the line, just like we did for Windows.

I’ll look at this some more but yes the library we are using doesn’t allow us to use vectors

[alexhauser]

How about querying the "correct" dimensions for the icon from the system before setting up the NotifyIcon and then just providing the properly scaled pixel image?

[josegomez]

That may be an option not even sure where to start with that but I’ll take a look
