Package: bugs.debian.org Severity: normal Dear Maintainer,
In recent weeks I have had problems playing videos on youtube and certain gifs and videos on other sites. After booting, everything works normally, and after some time the problem recurs. Youtube videos will get stucking while loading until a message appears "if playback doesn't start shortly, restart your device." Other videos (e.g. https://imgur.com/bZ2Uy4W) will display exactly two frames and then freeze. If a progress bar is available (as on facebook) I'm then able to click to an arbitrary point in the video, which will cause more of the video to buffer and will display the corresponding freeze frame, but the video never actually plays. This occurs in all browsers (firefox, chrome, and torbrowser). What I've tried: I disabled hardware acceleration in all browsers; this did not help. I've disabled all addons in all browsers and started them in safe mode; this does not help after the problem has started. Restarting browsers does not help. I have a hybrid discrete and integrated graphics card and have blacklisted the driver for the discrete card (nouveau) - lsmod shows that nouveau drivers are not loaded anymore, but the problem recurred as usual. If I restart lightdm it *does* fix the problem, temporarily. Rebooting fixes the problem temporarily. I'm not sure how to proceed to isolate the problem.
