Created attachment 275819 [details] backtrace Steps to reproduce: 1. Launch minibrowser 2. Load https://blogs.gnome.org/mcatanzaro/ Expected results: WebKitWebProcess would not crash Actual results: WebKitWebProcess crashes (for me) 100% of the time: (WebKitWebProcess:19243): Gdk-ERROR **: The program 'WebKitWebProcess' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 177 error_code 2 request_code 154 (GLX) minor_code 24) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Environment: Fedora 23, GNOME 3.18.x, X11, unmodified WebKitGtk+ jhbuild environment (including jhbuild-built dependencies). I've attached a backtrace from debug build after doing what the error suggested.
Terminal spew I missed before (sorry for being noisy): libGL error: unable to load driver: r600_dri.so libGL error: driver pointer missing libGL error: failed to load driver: r600 libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast
Is OpenGL/glx working on your environment? What does "glxinfo|grep render" says? Can you try to: 1. export WEBKIT_DISABLE_COMPOSITING_MODE=1 2. Launch the minibrowser Is the problem still reproducible after setting that environment variable?

The machine in question now has F24 and no crash. $ glxinfo | grep render direct rendering: Yes GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, Extended renderer info (GLX_MESA_query_renderer): OpenGL renderer string: Gallium 0.4 on AMD RV730 (DRM 2.43.0, LLVM 3.8.0) GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_packed_depth_stencil, GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth, GL_NV_blend_square, GL_NV_conditional_render, GL_NV_depth_clamp, GL_OES_element_index_uint, GL_OES_fbo_render_mipmap,
I'm hitting this again (now on fedora 36). And, yes, setting: WEBKIT_DISABLE_COMPOSITING_MODE=1 Does indeed solve the problem.
