Eventually garbage collector should free the memory What happens instead? Memory is not freed. Please provide any additional information below. Attach a screenshot if possible. I have this issue only if I get image data from canvas. I didn't try any other types of arrays to see if there is a difference -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
