Created attachment 384908 [details] photo of gdm gnome 3.12.2 env works ok when VIDEO_CARDS="intel" when I change VIDEO_CARDS="intel nouveau" to build a nouveau driver to make use of my optimus-based laptop, I experience issues with gnome and gdm rendering on intel. The rendering result on screen differs from what is captured in screenshots. Please refer to the attachments for coomparison.
Created attachment 384912 [details] screenshot of gnome desktop 1 (normal) This is how the screenshot looks like. Screen shows a different picture
Created attachment 384914 [details] photo of gnome desktop 1 (screwed) Here is what I see instead of screenshot desktop 1
Created attachment 384916 [details] screenshot of gnome desktop 2 (normal) Activities overlay looks normal in screenshot, but not on screen
Created attachment 384918 [details] photo of gnome desktop 2 (screwed) At first, when I press Super key, nothing changes at all. When I move the mouse over the positions of the icons on the left, they are repainted.

Please provide also /etc/Xorg.conf and /var/log/Xorg.0.log. How are you setting up both cards? Are you using bumblebee or what?
I use CONFIG_VGA_SWITCHEROO in the kernel to manage the power for nvidia card. Please have a look at https://bugs.freedesktop.org/show_bug.cgi?id=78092#c18 I don't have /etc/Xorg.conf - i.e. I rely on Xorg server to do the automatic detection of the hardware. I have no Xorg.0.log. all messages are in the common journal. Please see the attachments for Xorg.0.intel (for no nouveau driver) and Xorg.0.nouveau (for problematic config)
Created attachment 385002 [details] Xorg.0.intel - all working fine
Created attachment 385010 [details] Xorg.0.nouveau - rendering issues
Is this still a problem with Gnome 3.16 and updated nouveau driver ?
I can no longer observe/reproduce the problem. I'm on Gnome 3.16.2 now.
Nice to know, thanks for feedback
