VLC still decorates its transient window even when explicitly given the NakedTransient style

[nguyenhuy-hoanganh]

Upfront Information

• Fvwm3 version: 1.0.5 (1.0.4-128-gc7b41a03) installed from the fvwm3-git AUR package

• VLC version 3.0.17.4 Vetinari (3.0.13-8-g41878ff4f2) installed from Arch's Extra repo

• Linux distribution: EndeavourOS Linux x86_64

• Kernel: 5.18.3-arch1-1

Expected Behaviour

I set the DecorateTransient Style to all windows with Style * DecorateTransient
I explicitly gave the NakedTransient Style to vlc with Style vlc NakedTransient

My current configuration for transient windows is as following:

Style * RaiseTransient, LowerTransient, StackTransientParent \
!FPGrabFocusTransient, DecorateTransient

Style vlc * NakedTransient

Now transient windows in vlc should not be decorated at all...

Actual Behaviour

But after turning on fullscreen mode with vlc's built-in fullscreen function, the transient playback progress window still receives decorations.

This behaviour can be replicated with the default fvwm3 config that comes in /usr/share/fvwm3/default-config/config , after you
supplement it with these specific Style settings, of course.

Hi @kittywritescode

Can you confirm the window in question really is transient? You can use FvwmIdent.

[nguyenhuy-hoanganh]

Unfortunately the progress bar in fullscreen vlc does not really stay put when trying to check its property with FvwmModule, but I can infer that it is indeed transient, because when I set the style NakedTransient to all windows, it does not receive decorations, but when I set DecorateTransient to all, it does receive decorations, but as I said, explicitly setting vlc to NakedTransient does not turn that off.

EDIT: Let me reclarify: When trying to enter Fullscreen mode with VLC's built-in functionality, it is not possible for a FvwmIdent window to show up, which makes it extra hard to check its properties. VLC has two kinds of "Fullscreen mode". One is a typical fullscreen mode that you can press F11 to go in. The other is only accessible while watching a media, and then right click > Video > Fullscreen to fully hide all the bars and menus. This second type of fullscreen is what I'm having issues with.

Update: I have managed to make the configs work how it is supposed to again. I suspect I must have left out a comma separating different styles earlier. Issue can be closed
