I had same issue, turned FXAA off, seems now that blur effect is gone. Nvidia 430.26, 4.15.0-54-generic, GeForce GTX 1060 3GB
Attached example screen capture comparison so it surely not my display problem, graphics raster really gets blurred. Issued same problem also years ago if I remember right. ** Attachment added: "vitunouto.png" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1294762/+attachment/5302125/+files/vitunouto.png -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1294762 Title: Blur effect on whole screen To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1294762/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
