transform tools with alpha images - Brownies323 - 03-26-2025

hello
i have used gimp for as long as i can remember, but this version 3 is giving me an issue i cant figure out how to fix

i use multiple layers often and using "color to alpha" so i have transparent backgrounds etc...

up til now its never caused a problem... so here what i do
add alpha channel - erase parts of some images,  then color to alpha... ok all good up til this point... now i use transform tools to move, resize and tweak images etc...

so example, once i have used "color to alpha" i select the "scale" tool
soon as i select the layer with it, its like a revert back to pre "color to alpha" but, this is only while the tool is selected, the image still has the transparency once task is done, but how do i choose to not see this while transforming??  version 2.10 did not act like this
for the life of me i cant see any settings to change this

i use the tools so i can see where i am placing images and overlaying etc... with this showing i can not see

please help???

It is Gimp 2.30 layer effects - that little fx icon in the layer dock.

(1) If you want "As Gimp 2.10" then when a dialog such as Color-to-Alpha has a Merge Filter icon then enable it. 
(2) For your (very small) example you can go layer-by-layer,click on the fx and merge any effect.
