Picture in Picture lock up computer
Picture in Picture is very unreliable on my system. Sometimes it works fine, more often it pops out a black square with no video in it, occasionally it locks up the whole computer. Basic system info; Dell Inspiron 620, 3Ghz 4-core, *GB RAM Integrated video Linux 64 bit Mint 18.3 Kernel 4.15.0-142-generic Firefox v 88.0 (yes I know there is a newer one, but I cannot upgrade via Mint software update right now. In any case this has been going on since PnP was rolled out)

Picture in Picture is very unreliable on my system. Sometimes it works fine, more often it pops out a black square with no video in it, occasionally it locks up the whole computer.
Basic system info;
Dell Inspiron 620, 3Ghz 4-core, *GB RAM
Integrated video
Linux 64 bit Mint 18.3
Kernel 4.15.0-142-generic
Firefox v 88.0 (yes I know there is a newer one, but I cannot upgrade via Mint software update right now. In any case this has been going on since PnP was rolled out)

Can you provide steps and website to replicate the issue?
KDE or Gnome?
The following examples starts firefox and stores the strace output(o option)to firefox_txt file with time stamps(t option)on each line. You can then check the output for errors.
The screenshot is an example to trace firefox via the process id.
strace -to firefox_txt firefox

Sorry, I thought the included system output would show the desktop. It is MATE: mate-desktop 1.18.0-1+sonya amd64 Library with common API for various MATE modules It is running on Linux Mint 18.3 I would attach the requested strace output but I see no way to do so here. I hope I did it correctly, I had to modify your example slightly to get it to work: strace -o firefox_logs -t -p 1976
I did not get it to lockup the computer this time, but the PinP window was a black rectangle, and could be dragged up the screen on and on. I did get it to show the video once, but many other trys just resulted in the bIack rectangle. I will attach a screenshot. Thank you for your help.
Not thinking, maybe this link will work for the strace ouput: https://drive.google.com/file/d/1T8sBWSWjZ54Cs4-wr1SFJ4naJQ9m13eK/view?usp=sharing
It works for me. see screenshot Try updating to the current version and verify that your ffmpegs and other dependencies are up to date.
