This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release. Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release. This request is not yet committed for
Same as fedora bug 566971
This is a crash inside the AMD Catalyst drivers; it might be related to the specific code in the desktop-effects tool but the code is working fine with other drivers; more likely it's a general crash on the affected system for any OpenGL program. desktop-effects has a very small usage of OpenGL - it just creates a GL context, queries information about available strings and then closes everything.
There's not much we can do to debug it since the crash is inside fglrx.
(There's a small chance it's related to bug 574500. The Catalyst drivers might not handle the case where we try to create a GL context after a failing call to XCreateWindow, and might segfault instead of correctly relaying the X error. I don't, however, think that's very likely.)
Development Management has reviewed and declined this request. You may appeal
this decision by reopening this request.
