Comment 0 for bug 1827194

When you have been playing a subtitled mkv file for a while and try to load a new subtitled mkv file in the same instance of Totem, the UI freezes.

You must let the video play for a while for the problem to manifest. I don't know how long exactly, but ten minutes should do it. Loading file after file in quick succession works fine, and it doesn't happen if you seek forward in the file to go to a later time in the video. You have to actually watch the video for a while for it to happen.

This problem has been in Totem in for the past several versions of Ubuntu, but in 19.04 the problem has slightly changed: Totem used to become completely unresponsive and you had to force quit it, but in 19.04 you can click the close button and it closes immediately. Other than that, the problem is the same: all you get is a frozen black screen.

This problem could affect other file formats as well, but subtitled Matroska files is what I've personally been affected by.
