Sotaro, can you reproduce this?
Yes, I could reproduce the problem. When I implemented, it did not happen such often:( There are some workaround to suppress it. Then it is a regression of Bug 1602643.
Crash of Bug 1624817 could also happen. If the crash happen, it also could cause similar effect.

It seems that a change after Bug 1602643 seems to made the symptom very often.

When I forced to do WR rendering twice during disabling WR native compositor. The problem was reduced for me. I wonder if it could be a short term fix.

It seems that first rendering to SwapChain was not used by IDCompositionVisual2.
