I have been using TBH20 for a long time without any problems. However, I recently took a break from using TBH20, during which time I downloaded some new games, and then there was a bug when I used TBH20 again. The brush and stage will not be displayed properly, the brush will be faulted, and the stage will become tilted. I also tested TBH17 and TBH21, which had exactly the
same problem. I don’t know what went wrong.
