Summary0017400: Playing YouTube video causes MM to terminate slowly and to lose UI settings
DescriptionWhen the user plays a video in YouTube and modifies the view setting (changing from Full Window to Preview and narrowing the width of the Preview window), MM takes a long time to close and on restart, the changed settings are lost! Tested in portable mode. Performing similar tests when playing music do not result in this issue.
Steps To Reproduce1 Run MM (tracks by Charlie Puth [Online] displayed)
2 Double-click on Track 1 from the list of YouTube tracks
3 Move the MM window
4 Play next track
5 Switch from Full-Window to Preview mode
6 Play next track
7 Switch the width/height of the Preview window
8 Close MM
--> It takes MM about 3-4 minutes for all processes to close
9 Restart MM
--> All settings changes made in steps 3, 5, 7 are lost

Note: Performing the same tests using music tracks from the library doesn't trigger this problem
Additional InformationI wonder if this might in some way be related to 0017072 since in that bug, the delay in terminating MM also occurring when MM was stuck at 'Waiting for renderer' in the log.
TagsNo tags attached.
Fixed in build2297

Rusty, please install 2296 and replace both MediaMonkey.exe and MediaMonkeyEngine.exe by these:
Check whether the issue still occurs and generate new debug log (in case you can still replicate)

Tested this in numerous scenarios. This issue seems to be resolved.

Note that in the course of playing many videos, MediaMonkey can open multiple MediaMonkeyEngine instances (I've seen 4 of them), but they all close within about 15s.

Re the MediaMonkeyEngine instances: I see the same when playing YouTube video.
There are up to two additional MME.exe instances running.

Debugging it I see that the command line is
MediaMonkeyEngine.exe --type=utility --field-trial-handle=2704,5609970560872385186,4278017662158408910,131072 --disable-features=IsolateOrigins,site-per-process --lang=en-US --service-sandbox-type=audio --no-sandbox --locales-dir-

Petr indicated that it is an utility process run by Chromium and so far we don't know how to prevent Chromium from running it. Based on this it looks that Chromium can create up to 5 such an additional utility processes. These two additional utility processes are with params --service-sandbox-type=audio and the other one with --service-sandbox-type=network .. by evidence needed for the YouTube playback.

BTW: The Skype also utilizes the exaclty same set of processes:
(so seems also running under Chromium).

Verified 2297

I am unable to replicate UI loss of settings. Test note non debug version closes 2-3s faster anyway.
