Description of problem: If I view certain PDFs in Firefox with the built-in PDF viewer, something causes all sorts of nasty display corruption affecting every X program. This seems like it might have security implications since a standard X client is doing standard things and somehow manages to seriously freak out the server and/or other clients. Version-Release number of selected component (if applicable): xorg-x11-drv-nouveau-1.0.6-1.fc18.x86_64 xorg-x11-server-Xorg-1.13.3-2.fc18.x86_64 kernel-3.8.4-202.fc18.x86_64 mesa-dri-drivers-9.1-3.fc18.x86_64 How reproducible: Every time. Steps to Reproduce: 1. Using Firefox with the built-in pdf.js viewer enabled, visit this link: http://adsabs.harvard.edu/cgi-bin/nph-data_query?bibcode=1984ApJ...279..763N&link_type=ARTICLE Actual results: As soon as the PDF finishes loading, all sorts of crazy display corruption everywhere. Can sometimes be fixed in individual apps by closing and restarting them, but often the shell itself is affected. Expected results: Uhhhh ... not that. Additional info: I'm on a Lenovo T530 laptop. Nouveau reports chipset "NVIDIA NVc1". lspci says "NVIDIA Corporation GF108 [Quadro NVS 5400M]". This only started happening about 6 weeks ago. When it began, I tried booting into an older kernel version but that didn't help. Whatever change caused these problems also made it so my laptop can no longer drive my external display without some other memory corruption issues. Viewing the PDF in Evince doesn't cause problems. The specific nature of the PDFs that cause the problem is that they contain full-page monochrome scans.
Created attachment 731433 [details] Screenshot of corrupted Firefox window. Note that all the icons are messed up. Firefox is in fact still usable and I'm entering this information in the same instance. Not shown in the screenshot is the rest of my desktop, which has similar issues. My desktop background appears to have been scribbled over aggressively.
Sorry, one more followup comment. I went to verify that my example link triggered the problem and in this case I did have to scroll through several pages before things blew up. But, as shown in the screenshot above, they did blow up.
I was able to reproduce this problem as well on my new Lenovo Thinkpad T530 by simply viewing the PDF as well. (not sure if I want to thank you for that or not <g>) I also have the problem happen when changing the wallpaper as well via Nautilus.
I had been hopeful, but this problem is definitely still present in the Fedora 19 alpha. xorg-x11-drv-nouveau-1.0.7-1.fc19.x86_64 xorg-x11-server-Xorg-1.14.1-1.fc19.x86_64 kernel-3.9.1-301.fc19.x86_64 mesa-dri-drivers-9.2-0.1.20130508.fc19.x86_64
With the official Fedora 19 release + updates, it looks like this problem is gone. PDF viewing hasn't caused any problems for a while. Seeing as there hasn't been any developer response on this anyway, I'm going to go ahead and close. xorg-x11-drv-nouveau-1.0.7-1.fc19.x86_64 xorg-x11-server-Xorg-1.14.1-4.fc19.x86_64 kernel-3.9.9-301.fc19.x86_64 mesa-dri-drivers-9.2-0.12.20130610.fc19.x86_64
