Hi Plunskas! It's actually an expected behavior when you are manipulating cels (like in your example), it looks like you are expecting the behavior of dragging frames (you can select frames dragging the mouse in the numbered header):

All the details in our forum announcement:
community.aseprite.org/t/aseprite-v...

There is a little option in View > Preview > Hide Other Layers that will show only the active layer in the Preview window.

🥹 those animations look gorgeous, congrats for the great work you all are doing and thanks for the little gift of showing some of the backstage 🥰

Sorry about this, it should be fixed now 🙏

😭 sorry about that, you can still use the old Edit > Insert Text menu option, anyway in a not so far future we'll introduce Text layers for better control

More info in our blog: blog.aseprite.org/2025/09/23/a...

👏

there are plans and some work have be done about the UI design, no ETA yet :'(
