In addition to in slideshow mode in libreoffice, I confirmed this problem when playing high bitrate movies in fullscreen mode (any movie players).
Interestingly, a mp4 movie pasted on a slide in libreoffice that hangs the GPU doesn't induce the same problem when it is played on a movie player. However, playing a high bitrate (say, a DVD iso) movie on a movie player hangs. Probably it occurs when GPU gets high load or sometime of buffer overflow (speculation). Perhaps this is a duplicate of other bugs observed on haswell's integrated GPUs. thanks. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1243261 Title: apparent GPU hang on haswell laptop when playing movie on libreoffice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1243261/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
