Bug Report Crash with OBS / OBSMP + CLR Browser / Browser Source

[goldenh]

Seems like when the Browser source creates a popup window, if you navigate away from that scene or scene collection, then back, before dismissing the dialog, when you do OBS will crash.

I happen to be using this site: http://e.ggtimer.com/1 minutes

OBS becomes unresponsive but will continue streaming until you press the 'OK' button a second time, then it hard crashes. OBS-MP reports a crash, and appears to remain responsive, but will not actually close or allow you to copy the crash log into the clipboard.

As long as you don't press the OK button you can have five or six different popups and OBS will continue to respond normally.

I would guess this has something to do with the plugin not being closed properly when it launches a popup. An option to disable popups in the plugin would be a great workaround.

I made a youtube video of myself reproducing the crash: https://youtu.be/tpRBtz__vK4
And attached crash logs from both OBS and OBS-MP

Does the page you're trying to use work in chrome?

 

[goldenh]

@Harold yes, it has no problems in chrome. I can visit the page as many times as I want without incident.
