Hi, when I run the FlattenPictureTest in the test environment, it always runs through in an absolutely reasonable time. On Haiku, the whole system is brought to a crawl, the execution time of the test is unbearable, but eventually, it always finishes. Any clues? Since running this in the test environment works, I'd suspect app_server is not at fault, maybe some low level stuff (ports?) that we inherit from the host BeOS system in the test environment? Best regards, -Stephan
