Hi, I have no test case, I can only show you our software which renders slow when using BufferedImages and which renders fast when using VolatileImages on JDK7/8/9.
Additionally I recently found that it renders faster when using BufferedImages and setting property „-Dswing.volatileImageBufferEnabled=false“ to false… Best regards, Tobi > Am 05.08.2014 um 15:39 schrieb Sergey Bylokhov <sergey.bylok...@oracle.com>: > > Hi, Tobias. > Can you share the test case, which will show that a BufferedImage is not > cached using VI. > > On 05.08.2014 11:32, Tobias Bley wrote: >> … >> >> So my conclusion is: JDK7 and JDK8 are not in beta stage and not finished on >> Mac OS X!
