When the flame graph type is switched from On-CPU to Mixed. It still show the graph of On-CPU.
h2. Root cause:

When click the other types, the web frontend will call the requestFlameGraph and update the graphType. However, the graphType is the old type during requestFlameGraph. So the graph type show the new type, but the flame graph is the result of old type.
