FX affect all frames

[dacap]

Welcome @Ara, from your video it looks like this issue is related to the “All” option in the “Brightness/Contrast” dialog (you can click it to change it to “Selected”):

Replace Color: Where is the "Apply to all frames in the active layer" button?

I’m preparing a fix to this (bringing back a simpler version of the button), but at the moment you can select all layers and use Replace Color to replace the color in whole sprite. (You can Shift+click the layer where you want to see the Preview too.) [51] [58]
