vlc/twm/bionic don't interoperate

[gregrwm]

vlc/twm/xenial no problem.
vlc/twm/bionic can't adjust time slider.
vlc/lubuntu/bionic no problem.

When positioning the pointer over the time slider, a little window appears showing the time under the pointer. With the vlc/twm/bionic combination, that little window has a title bar containing "Untitled", thus the little window hangs down over the time slider, and moves with the pointer, so clicking on the time slider is impossible.

i doubt twm has changed in years. That's one of the benefits of using it. Along with microscopic footprint, several features still unimplemented in any other window manager, and still considered the reference standard window manager implementation for xorg.

my bionic install currently has a networking issue (bug 1748409), so i filed this bug under xenial, but the bug is in bionic, not xenial.

I would hazard a guess that this is a problem between Qt5 and TWM, not VLC per se... And even if it is blatantly obvious which one of those two has changed, I would not hazard a guess as to which one is at "fault".

Reassigned accordingly.
