Describe the bug

The cam is displayed with a window frame and title, despite selecting "Remove window frame".

To Reproduce Steps to reproduce the behavior:

Go to Cam > Select a cam from list
Click on Remove window frame (toggle activate)
The cam window is displayed with a frame

Expected behavior The cam window should be shown without a frame

Additional context

this used to work in the previous version (probably 3.8, not sure because I didn't use it for some time)
the problem appears irrespective of the camera settings like encoding, resolution
the problem appears irrespective of the cam window setting like square, ellipse, round, or scaling

Screenshots This is the screenshot of the cam window following the "remove window frame" is toggled active. The time of toggling the option does not influence the result. Note the window background is in fact transparent.

I found a workaround to remove the window title selectively using the following command shell alias:

# added to .bashrc
alias vokome='xprop -id $(xdotool search --name "Camera ") -f _MOTIF_WM_HINTS 32c -set _MOTIF_WM_HINTS "0x2, 0x0, 0x0, 0x0, 0x0"'

Then I can start vokoscreenng 4.0 and just type vokome in my bash shell to removed the window title, as would be expected. Perhaps this is helpful in resolving the issue. The workaround is inspired by https://unix.stackexchange.com/a/446519/477548
