Because this normally happens after first boot, but not in posterior ones, I greatly suspect this is a hardware bug.
Probably this is happening because of the GPU passing from a cold state to a warm state too fast, under graphic demanding operations as watching videos are. And Windows users won't be experiencing this as the GPU doesn't stay in a maximum power state all the time. So this should be a bug in the Linux kernel, Direct Rendering Manager's, Dinamic Power Management feature. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/881526 Title: AMD graphics hardware hangs with an homogeneous coloured screen or blank screen, and with chirp coming from the graphics card To manage notifications about this bug go to: https://bugs.launchpad.net/mesa/+bug/881526/+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
