The other finding for comment#20. If connecting two monitors then there is a way to reproduce it.
1. Set iGPU as primary monitor 2. Run an application from secondary display (dGPU) (e.g. glxgear) 3. Moving the application from secondary display (dGPU) to primary display (iGPU) then the issue occur. For comment#19, I'm preparing hirsute using today daily build. Will update the result here later. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1923153 Title: [radeon] Display output laggy from iGPU when operating on desktop with attaching AMD R7 430 graphic (dGPU) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1923153/+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
