I don't follow why this was moved from performance to platform. The error is either in the performance tracking tool or
in jdk's native calls.

reassigning to winsys guys, a likely candidate for "invalid/wontfix" issue.

Comment 3 Jaroslav Tulach 2009-08-05 10:24:32 UTC

There seems to be a lot of such slowness reports. They happen on GTK only. So I guess the snapshot tool is giving us 
consistent results, nothing random. We definitely seek help from our Swing gurus (thus assigned to platform/window 
system). If there is nothing NetBeans can do, then please help us report this issue to JDK team and mark as a JDK bug.

Btw. slightly suspicious is that the problem often happens when painting Tabs.

Comment 4 Stanislav Aubrecht 2009-08-05 10:34:15 UTC

swing guru says: the bulk of wait time is in native paint methods (nativeFinishPainting) nothing to fix here
so it's either a bug in graphics driver or a bug in jdk, note that reported jdk version is 1.6 *update 0*

Showing the part of snapshot that ends in GTKEngine

Comment 6 mslama 2009-08-20 12:12:56 UTC

Is this reproducible? I see it is reported for Open JDK - does it happen also with Sun JDK? Is it multi display setup?
Could I send you patched module so that we can see what input values are passed to GTK paint method?

Comment 7 mslama 2009-08-20 12:18:24 UTC

In issue #169817 this happens with Sun JDK.
