Borderless fullscreen windowed mode
Is your feature request related to a problem? Please describe. It's not really addressing any specific problem, I would categorize this instead as a matter of ease of use, especially when switching between Stellarium and other windows on the system.
Describe the solution you'd like I would like to be able to run Stellarium in a borderless fullscreen windowed mode, which visually would be presented as is the default fullscreen mode, covering the task bar, etc., but allowing to seamlessly ALT+TAB between windows without entering and exiting the exclusive fullscreen mode, as is the case with the latter. This would resemble the behavior that happens when using ANGLE, but in this case it would not require ANGLE for that purpose.
Describe alternatives you've considered None, beside using the software in ANGLE mode, or in standard window mode with the downside that it has the title bar and doesn't cover the whole screen resolution (ie: taskbar). You can manipulate the windows with tools such as Borderless Window Utility, to force the window to become borderless, but it still will not be able to cover the taskbar. Regardless, it would be great if it could be done natively
Example of the current window maximized
Forced borderless window (still cannot cover taskbar)
Thanks for adding your first issue to Stellarium. If you have questions, please do not hesitate to contact us.

Just an observation: I recently tried Stellarium in a different system and there the standard fullscreen mode worked seamlessly without a black screen transition whenever ALT+TABing out or into Stellarium.
Both systems have the same OS, but different CPU/GPU. The one with the black screen transitions is an i7-8700T w/ UHD Graphics 630, the other is an older i5-3470 w/ HD Graphics 2500.
Hi, how can I turn my stellairum in this mode? (Bordless window) @ner00
@parsifal7366 This issue requests a feature for having borderless window mode, it doesn't exist in Stellarium as of yet.
I also mentioned that seamless desktop/fullscreen depends on hardware/driver: https://github.com/Stellarium/stellarium/issues/2472#issuecomment-1147266316
If your question is aimed at the second screenshot, which I simply used as an example, I used Borderless Window Utility to demonstrate what I was requesting: https://github.com/banzify/Borderless-Window-Utility
As far as I can tell, https://github.com/Stellarium/stellarium/pull/2619 doesn't fix this behavior.
Also, Angle mode still doesn't work out of the box, but iirc Angle will be discontinued so I'm not even really too much hung on that detail. Alt-Tab in/out of Stellarium still makes the screen flash as if there is a screen resolution change (although there isn't).
As far as I can tell, #2619 doesn't fix this behavior.
did you add "--single-buffer" to the command line? (Qt6 builds only)

I tried it, doesn't seem to cover my issue, although I'm unsure if we're talking about the same thing. I see a lot of complaints about screen flickering in some of the issues linked to the PR, my issue is not flickering.
PS: My understanding is that the QT6 build for Windows failed, so I can't test that.

I see you are using the Qt5 based build. Unfortunately, the "--single-buffer" switch has no effect here. Hopefully tomorrow stellarium-1.22.2-0511533-win64.exe based on Qt 6.3.1 will be available for download...
Flicker is perhaps a misleading term in this context. As far as I can see, the graphics processor switches to an exclusive mode that may be intended for computer games. When switching, the backlight of the monitor is turned off for a relatively long time. This looks particularly annoying. I read exactly this behavior in your description. So I still have hope...

@uwes-ufo You were right, the single buffer switch fixes the video mode "flicker" on my GPU. Thanks!
