gregrwm, this report is being closed given you updated to Bionic, and you have not advised to further occurrences with either VLC or Firefox.
However, please focus your efforts on one bug/report (LP#1757299) so that it may be root caused and solved, versus commenting across multiple reports, or making new reports about potentially the same issue. Doing this causes confusion, and delays your issue being resolved. Thank you for your understanding. ** Changed in: xorg (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1744429 Title: [Dell OptiPlex 755] PC freezes while playing vlc or youtube Status in xorg package in Ubuntu: Invalid Bug description: When watching youtube or vlc, xorg CPU utilization increases, until overall CPU utilization pegs at 100%.
