I just want to write this message for anyone who encounters the same issue as me because I spent over 4 full hours debugging this issue. If you are using any of the pan plugins ([Pan - Notes of Phaser 3](https://rexrainbow.github.io/phaser3-rex-notes/docs/site/gesture-pan/#create-instance)) or just changing `camera.scrollX` or `camera.scrollY` values to pan a game camera, make sure you also set `camera.setRoundPixels(false)`. Setting it to false is not enough in the game config.

This example shows the bad behaviour when you try to pan slowly.
