Haha! yes! I can see the content now, on intel.

I cannot load the file on nouveau where it was captured, it says

 | 2 @0 eglGetPlatformDisplayEXT(platform = EGL_PLATFORM_GBM_KHR,
native_display = 0x26926b0, attrib_list = {}) = 0x26d8250
 | 2: warning: unsupported eglGetPlatformDisplayEXT call
error: failed to create OpenGL 3.1 context.

Same links, updated files:

For example frame 8932 (toward the end) is interesting imho, because it shows
the icon looks wrong (which is what led me to this issue in the first place).

But the rest of the window looks fine on intel, which is not what I see on
nouveau with the G71, it looks all garbled there (as in attachment  128933)
