Under Arch linux, upgrading from xorg-twm-1.0.9 to xorg-twm-1.0.10 did the following:
- twm windows title bars are not visible
– windows cannot be moved/set onto foreground/background
- all menus from firefox (v59), including contextual menus, disappear as soon as clicked making them unusable
It is very similar to starting X with twm uninstalled. However I could observe that the twm process was running.
I noticed that replacing the /usr/bin/twm binary with the previous version fixed the problem.
I have no ~/.xinitrc, nor ~/.twmrc.
