Comment 1 eddy02 2016-06-08 07:14:57 UTC 
Testing chromium from copr give  nearly same results blank and white pages.
Comment 2 Rex Dieter 2016-06-08 11:53:42 UTC 
The same (source) build works fine on f24, so the issue is likely some external issue specific to rawhide :(

If you could get a backtrace with debuginfo, it may help give some better clues.
Comment 3 Kevin Kofler 2016-06-11 22:11:51 UTC 
I built qt5-qtwebengine-5.6.1 and qupzilla-2.0.1 for Rawhide, do these work any better?
Comment 4 eddy02 2016-06-12 08:27:24 UTC 
Qupzilla hangs (nouveau driver fifo and dma errors) and qtwebengine segfaults later.

I'll revert to the nvidia blob and make a retry as since kernel-4.6 I can't run  qtwebengine with nouveau driver without crashing.

Thanks for your builds and sorry for my english.
Comment 5 eddy02 2016-06-16 09:30:05 UTC 
Latest Rex koji build solve the issue.
Qupzilla works again.

Thanks very much.
