[W10] taskbar icon can disappear, effects of replacement

[Porkepix]

Description

When opening other windows such as settings one and then closing it, there is some "replacement effect" where there's a visual effect showing the taskbar icon being replaced by something else.
Sometimes, what comes to replace… have no icon at all.

Steps to reproduce

Repro rate is not 100%.

1. Open settings
2. Change for example language
3. Close settings
4. There's this taskbar icon replacement effect, and sometimes it replaces with something with no icon.

Reopening and closing settings after this reinstate the icon. But we can trigger the bug again after that.

This is a screenshot of… Mumble in the taskbar when the bug istriggered. Unfortunately I found no way of having the preview when hovering while taking the screenshot.

@Hartmnt is this also fixed with your status bar icon rewrite?

[Hartmnt]

@Krzmbrzl Can not say for sure as I did not know about this problem on Windows before. But given that the tray icon implementation will be essentially rewritten entirely, it is more likely than not fixed with my PR. I guess OP has to test it at some point :)

It seems there might have some misunderstanding here.
My issue is not about the notifications tray at the bottom right of the screen.
It's about the large place at the bottom of the screen where the currently opened softwares are sitting.

Ah I see. So this would be a different problem then. Possibly related to the application icon maybe 🤔

I just did new screenshots and enabled the text usually disabled to make it more clear:

Without bug, the icon is here:

I triggered the bug, icon has gone missing:

Note that when the icon goes missing, there's this "replacement" effect with a slide, while when I get the icon to come back it just reappears without any effect.
