Created attachment 45902 [details] patch
I believe the attached patch should help for at least JA2. There are probably some more places where we assume the front buffer is always a render target though, so the patch may not help for some of the other games you mention, and there's a chance 6f321ff2f97a4eb1e613022342399c3ffc41bc89 is going to come up for future regressions as well.
Thanks, the patch fixes the problem in JA2 as well as in many other games affected by this regression.
