The Alt-Tab display

[timboalogo]

Hi, another silly question perhaps but a curiosity nonetheless.

This didn't happen in CbB but does now in registered Sonar: I create a new project, load a VST (e.g. Scaler). I leave the project and alt-tab through my active programs, and although Sonar is closed, I see 2 windows that I can alt-tab to (although nothing happens when I do): 1) a small one that looks like a title bar Scaler 1 2 (Untitled Project1), and 2) a fuller sized one with a black background called Scaler 1 2 (Untitled Project1). 

When I repeat these steps in CbB, the 2 ghost windows do not appear after CbB has been closed.

I'm wondering if this is a Windows 11 bug or a Scaler bug or a Sonar bug. Can anyone else reproduce this?

A bump before this post goes to oblivion. Can anyone reproduce this?

Not sure if related but I have noticed there can be undocked windows that are very hard to see/find because they are sized down to a tiny title bar (not Minimized, but rather "smallest size"). Once I do find the tiny title bar, I click/drag edges to properly size the window then that solves the problem.

I have had this exact issue at least since May, 2025. The number of Alt-Tab boxes varies. Most of them seem related to one plugin or another. I submitted a request about it. Jumped through the usual hoops - re-installing Sonar and taking screen shots, etc. Never got a resolution. And with other flakey stuff happening with my Sonar I can't help but wonder if it's related to this issue.
