Online, just now noticed some websites are coming up ok, but then charac ters rapidly begin to disappear or get replaced by wrong characters. If I click on any words in this post several times, the missing characters "Kr" intermittently appear in the example above and disappear in this sentence. Also just noticed that same behavior occurs when I move the mouse in and out of the text pane. Very odd. Some menus are corrupted too, Evolution (mail). System was working before the updated nouveau driver. I never installed NVIDIA drivers. System Fedora 22 32-bits with GeForce GTX 745 -- Rudolf Künzli <rudolf.kunzli at gmail.com>
