Screen scrambled when pressing Alt-F9 under Windows 11 22H2

Far Manager version

3.0.6037.2930 x64

OS version

11.0.22622.730

Other software

When you maximize with Win+Arrow Up - it works.
When you maximize with Alt-F9 screen looks scrambled.

Steps to reproduce

• Install Windows 11 22H2
• Install Far 3.0.x up to 6037.290
• Press Alt-F9

Expected behavior

Window maximized, screen not scrambled

Actual behavior

Window size remains, screen is scrambled

Far calls GetLargestConsoleWindowSize when you press Alt+F9 and that API is broken in Windows Terminal.

Maybe we will come up with a workaround one day, but so far it is what it is.

Since Win+Arrow Up is working... could this be a workaround? Simply maximize the window?

Is there a way to use the former (Windows 11 21H2) terminal window? Because what also bugs me is when I press Ctrl-V I'm asked if I'm sure I want to insert (by Windows) and then the pasting happens real slow...

Unfortunately, no. Windows Terminal prevents console apps from accessing its window (because its developers believe it is the right thing to do), so we cannot do anything with it.

I think I can come with a workaround to at least not scramble the screen though. 6038.

It is somewhere in settings.

[TheChatty]

Since window size doesn't change with Alt-F9 it would be best to simply ignore this.

[TheChatty]

I found that setting. But what works even better: Change your launching short to
C:\Windows\System32\conhost.exe "C:\Program Files\Far Manager\Far.exe"

Even Alt-F9 is working ;-)

And when I try to paste something... you guess it, it's just there in a blink of an eye.

It can be disabled somewhere in terminal settings too as far as I remember, as well as intercepting of other keys.

My suggestion is to ask the user during installation on 22H2 systems whether he wants a console or terminal app. I‘d make the former the default. If you don‘t want to ask make it default right away. 😉

[alabuzhev]

That's an interesting idea.
We might have to do that if the number of various terminal-related bug reports becomes unbearable.

[alabuzhev]

Alt+F9 should work from 6039 onward. Sort of.

[TheChatty]

With v3.0.6039.2932 pressing Alt-F9 looks the same as pressing Win+ArrowUp - and it works. No more scrambled terminal.

Nevertheless I'll stick with conhost - at least for Far Manager.
