Pixel Perfect Extension (D8H) bug

I am using D8H extension for the scroll camera because the Gdevelop built-in camera has jittering.

I am using pixel perfect extension aswell to have coordenates with integer numbers although I don’t notice for what, since my game resolution is 456x256 and always the pixels are alligned to that grid resolution regardless the resolution of the computer: 1080p, 720p…

Round pixels when rendering in Gdevelop game settings makes the same but only visually, keeping coordenates with decimals, so I don’t need it either for keeping alligned the pixels to 456x256 “grid”

However just in case I would like keep the pixel perfect extension but I have a bug related with the platform extension, I have create an example to reproduce this bug where it seems the default platform controls are working when they are totally deactivated from the behaviour menu.

To reproduce this bug you have to collide the playable sprite (black square) with the blue square.

The behaviour expected is a jump backwards on collision and after the playable sprite lands and stops.

The behaviour resulting, because pixel perfect extension is on, is a jump backwards on collision and after the playable sprite lands and moves forward.
