Is there a way to dynamically change an effect throughout the movie? Too many active WebGL contexts. Oldest context will be lost.

Hi, I'm trying to create a movie that consists of multiple image layers, to make a smooth transition between these layers, I want to use Gaussian Blur Effect of different radii to make a blur in - blur out kind of transition.
The layer order looks something like this:
image 1, blur of radius: 50
image 1, blur of radius: 25
image 1, blur of radius: 0
image 1, blur of radius: 25
image 1, blur of radius: 50
image 2, blur of radius: 50
image 2, blur of radius: 25
image 2, blur of radius: 0
image 2, blur of radius: 25
image 2, blur of radius: 50
...
However, I've met a limitation of "Too many active WebGL contexts. Oldest context will be lost.". Is there a way to apply a single Gaussian Blur Effect, but change its magnitude throughout the timeline? Other approaches to solving this problem are also appreciated
