MODIFICATIONS:

As vanilla as it gets

ADDITIONAL INFORMATION:

None

I also have to add that seeking is impossible (doesn’t work) and also on dark videos you cant see the buttons which is a UI/UX problem.

Could you add more information under the section Steps to reproduce?

Thank you in advance.

TBH i don’t know what to add to it. Use any of the apps described to play videos and you will get it once in every few tries.

So I can add more information. I encountered most issues with quickddit.

  1. Playing a video and especially GIF is super slow, it seems to consume so much memory all the apps in the background get closed and then the app the video is playing in gets closed too. For example this post makes quickddit and all the apps run out of memory: https://www.reddit.com/r/formuladank/comments/uz8fag/i_have_my_reasons/, when playing this GIF: https://i.redd.it/ueru6e0q63291.gif
  2. As for app hanging and not running out of memory, I know a way to make an app hand almost 100% of the time. When you play a video it first loads, which takes different amount of time depending on video type. When the video goes to the end, it starts to load again. When you exit the video view just as it starts loading again, you are almost guaranteed to make quickddit hang. If you do it a few times I am sure you can make it hang.

Both of those issues I encountered the most in quickddit, as Reddit containst the biggest variety of video formats. But they happen in all types of apps, just the easiest to replicate it in quickddit

Bumping this cause i am curious.

Is this one of those bugs that Jolla can fix or its beyond its reach -meaning deep in firmware code that cant do anything about.

Seeing buffer errors here reminds me that we have gst buffer errors in the volla port (frame buffers for video recording not being allocated or some such.). I wonder.
