NowKeith, I just read your other message. Ok, so let's call it "failure" ;-)I narrowed it down to tex[0], tex[1] and tcl states that appear to require 3D to be idle. Can someone with Radeon specs confirm this? OtherThat's exactly what you asked for :). More precisely, if TCL was disabled I had to wait before emitting texture changes. If TCL was enabled it was enough to wait before emitting TCL state. But this may be due to the order of state changes. If TCL state is always emitted before texture state, then waiting before the TCL state will also ensure that 3D is idle before the texture state change.
I've committed the first version for now, because
1) it's cleaner
2) it emits at most 1 wait per statechange
3) I'm not convinced that there are many statechanges that don't touch any of tcl, tex0 or tex1 -- ie I think the second version would emit a wait on *almost* every statechange.
If you want to narrow the lockup conditions down further, feel free & I'll commit the results.
Keith
