We have a title on Steam which is crashing quite often in aticfx32.dll - we can see this from the steam crash dump reporting system. From looking at the dump, the callstack shows we are calling dxgi::resizeBuffers, which is ultimately falling over in this code (between the ; vvvvvvv ;^^^^^^^ section

61833281 mov ebp,esp
61833283 mov eax,dword ptr [ebp+0Ch]
61833286 test eax,eax
61833288 je 6183328E

6183328C jmp 61833290

I have no idea (yet) what driver version this is but there's clearly something wrong with it.
I have suggested that users having this crash upadate their drivers.
