This is from editor’s preview.
This is from my android build.
I am adding blur effect to my base layer.
Yes it will happen because Build Services for android is not doing its job properly.
@Gruk had suggested me to disable layer effects but it didn’t work. 
You can see this thread 
Thanks.
I use blur image instead of adding blur effect to layer.
The blur effect should be removed from GDevelop.
Use the other effect instead. “Kawase blur” I think it’s called.

Yes its the fastest blur effect available and actually easy to understand.
