Description
FULL PRODUCT VERSION :
java 1.8.0_40-b25

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
As of build 40 for java 8 our programs display speed has dropped dramatically. We find that the time to paint an image or a string went from negligible to 4 or 5 milliseconds. Total time to paint graphics and strings on screen went from about 100 milliseconds to over 1 second.


REGRESSION.  Last worked in version 8u31


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Unfortunately, despite various attempts we have been unable to reproduce this problem in a small amount of code.

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Interestingly we found that avoiding double buffering avoids the problem. It comes at the cost of the display flickering, of course.


SUPPORT :
YES

I do not know, it was the first thought from where performance issue can occur.

Could you clarify a little bit more specific? If 8039444 is fixed will it change something for the current issue?

8039444 and related bugs are about default pipeline on windows.

Sergey, could you clarify how is it related to JDK-8039444?

Sent an email to the submitter suggesting to run with -Dsun.java2d.d3d=false command line parameter. ============================================================================= On 7/22/2015 9:00 AM, ........ wrote: > Hi ......., > > Could you check this with the latest JDK version 8u51? > Also, do start your application with -Dsun.java2d.d3d=false command line parameter and report back if the issue persists. > > Thank You, >.......... ============================================================================

The submitter reports decline in speed of display in version 8u40 and above when compared to 8u31. However, we don't have a suitable test case reproduce this issue. Moving this up for client team opinion.
