Online, just now noticed some websites are coming up ok, but then characters 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 in applications (Evolution, LibreOffic, etc.) are corrupted too, System was working before the updated nouveau driver.

What is a GTX 745? (I'm looking for a GKxxx or GMxxx model.) Are you using glamor? What bit of "nouveau" did you update? There isn't a single nouveau driver... (or any other GPU), it's lots of different bits and pieces. kernel, libdrm, xf86-video-nouveau, mesa.

Before kernel 4.1, unless you had extracted your own ctxsw firmware, you didn't have acceleration at all, that was likely the change that triggered the issue. The glamor integration in nouveau is, sadly, broken. But it's unclear whether that's the cause of your issue. You can either add Option "NoAccel" "true" to the device section in your xorg.conf, which will disable 2d acceleration and bring you back to the same state you were in before, or you can add Driver "modesetting" (or uninstall xf86-video-nouveau) which will use the modesetting driver which has a non-broken glamor integration. You may still get the same issues though, as they could just be generic mesa-sucks-on-maxwell issues (I don't have a Maxwell GPU, no one else has been interested in debugging/fixing issues). -ilia
Thanks - the only xorg.conf I found is - /usr/share/abrt/conf.d/plugins/xorg.conf Is this the file to be edited? -- Rudolf Künzli <rudolf.kunzli at gmail.com> On Tue, 2015-08-11 at 10:56 -0400, Ilia Mirkin wrote:> On Tue, Aug 11, 2015 at 10:47 AM, Rudolf Künzli < > rudolf.kunzli at gmail.com> wrote: > > > GeForce GTX 745 is a NVIDIA card in the NV117 (GM107) Family... > > The update was made using DNF (Yum) in my daily update procedure > > using > > the Fedora 22 Update repository. > > I am not familiar with details I just can report what happens right > > now... > > OK, there's no EXA support for maxwell, so you're using glamor. > Before > kernel 4.1, unless you had extracted your own ctxsw firmware, you > didn't have acceleration at all, that was likely the change that > triggered the issue. > > The glamor integration in nouveau is, sadly, broken.
