I assume I have some sort of memory management problem
I have great difficulties to visualise an entire S1 or S2. I have a very high end graphic card, plenty of RAM available etc. However, the tiling is not really working for the display. I am under Ubuntu 16.04 LTS with Snap 5
In this example, the left part of the scene would not load full resolution and most of the scene would not load at all.
I did not notice this problem when I started working with Snap and now it gets more and more common. Restarting snap seems to sometimes help but in this case it did not.
In which format is the product stored you are showing and how have you created it? It’s not a standard S1 scene. It looks like the tile size is very small. What is the size of the scene?
Can you show a screenshot of the about dialog, please? The available memory for SNAP is printed there.
It is a scene where I performed a stack. Originally 7 S1 products where processed individually and then stacked on one of them.
The product is stored with the standard Snap format BEAM DIMAP.
The file is still uploading and we reached almost 9GB.
So it could simply be that having 19GB is not enough memory to work with such big data.
Can you work with a spatial subset?
The File is 15Gb but I am only loading one band out of 9 I would suppose it should be equivalent to a single S1 scene
i will try to extract only the stacked band to see how it goes
I have tried to lighten the file by removing all the bands but the stack.
I get error messages concerning the bands I have removed. And it does not load.
I have also noticed that when you export a band calculated with band maths in Geotiff, it prompts a message telling you to include the bands you used in the computation.
No idea if this is linked. Here my current error message. Cannot log onto your ftp at the moment.

This is another issue. Probably the removed bands are used in the valid pixel expression of the remaining bands.
Regarding the original issue.
You can try to increase the cache size. At Tools / Options on the Performance tab you can increase this value. Set it to a value of 8000, for example.
I don’t fully understand your reply for the other issue. If I do band maths and I don’t make it virtual or I convert a virtual band. The data are saved (the file is 3Gb as a normal properly projected S1 scene). Why would it depend of the other bands from that moment?
