Unfortunately this is not an Option right now. but it might be in the future.

I will try this.

Unfortunately this is nothing we are able to change.

There are only 19 png files from 2 up to 100KB. So you are probably right, that
the Software adresses those files over and over again instead of loading them
once at the beginning.

As the files are really small I still would like to try hiding the error
message. Even this will probably not change anything. This might be the easiest
way to test for. So is there any way to stop the the console printout of the
errors?
