Hi, Emil Thanks for your reply.
I made simple tests. And maybe this patch should work. Because you can reproduce this problem, would you like to make tests with this patch? If this patch can fix this problem, it can prove that the root cause is correct. We can find another solution to fix this problem. If this patch can not fix this problem, maybe we should make further investigations to find the root cause. Thanks a lot.
