Issue description

Particle scale is not reset when a emitter shape other than point is set and a higher than default fixed_fps is used.
Combined with a curve for particle scale this will reused particles to be invisible.

Steps to reproduce

• Create a new GPUParticle3D Node.
• Set fixed fps to 144 (or 300 or anything high)
• Set it up to show something (rectangle is enough)
• Add a scale curve to the size parameter and make it go to 0 in the end.
• Set the emission shape to anything but point (eg. sphere)

I have been having similar issues. After adding a curve for scaling, all particles disappear, or maybe they have actually gone down to zero. Even if I then delete the curve, I cant see any particles any more.
