Thanks for the bug report. The attached files show the 'oibaf' PPA is in use (has replaced Ubuntu's official graphics packages) which is not supported by Ubuntu and is known to cause bugs.
Please remove the 'oibaf' PPA from the machine and if that does not fix the issue then open a new bug showing the problem in Davinci Resolve. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Invalid -- 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/2009293 Title: Amd Radeon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2009293/+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
