Hello!
For use with Post-Processing FX, the effect should be treated as an external effect, and added in the way described in the tutorial. The effect should be drawn by PPFX itself, rather than manually, so the resolution will be the same and the effect will work correctly.
Thank you for replying! I'm sorry to bother you with this - I may just be too inexperienced to solve this. I followed the tutorial you linked, but I'm unsure what you mean with 'the effect should be drawn by PPFX itself". After adding FX_Sketch to the xternal effects like the tutorial described I did this:
// CREATE EVENT
var effects = [
new FX_Sketch(true),
];
main_profile = new PPFX_Profile("Main", effects);
ppfx_id.ProfileLoad(main_profile);
// POST DRAW EVENT
ppfx_id.DrawInFullscreen(application_surface);
Is this wrong?

Edit: Actually, maybe this screenshot is more helpful: It is the Main menu and in the background there are background images from other rooms that should not be in the main menu: https://imgur.com/a/mFSqSQI
Ahhh okay, it's not exactly a bug, but the effect is displaying a texture page from the game, because some texture is not associated with the effect. I'm not sure which texture exactly, though... This didn't happen before, so either a GM update did this, or some texture is set incorrectly. Could you check if the textures for the effect are defined correct, and not defined to something like -1?
As far as I can see all textures seem to be defined correctly: https://imgur.com/a/PLQpVf
