In the last few latest releases, of Minecraft Bedrock Edition. Whenever you leave your world after it's raining, and then rejoin that same world. If you try and clear the weather, with the command /weather clear, the rain particles will remain in effect, even after running the command. The same also goes for snow as well. However, sometimes the sky will turn blue, indicating that the rain/snow isn't there, but the particles will still display on your screen. Now I did find a temporary fix. If you just leave your world and rejoin again, after the weather breaks. Usually, it will solve the problem. I'm unsure if anyone else has this problem, it could just be my game, but could you look into it please and thank you.

Also, so sorry for the video quality. I may have compressed it, a bit too much...
