Description pinus 2007-07-13 18:56:24 UTC
Using NB6m10 with JDK 1.6 on Linux is a real pain. Switching between diagrams takes a second or more, the java editor
tabs are much faster, nearly instantly. Selecting a component and dragging it somewhere feels like it is sticky.
Pressing the right mouse button may need a second to display the menu. Double clicking a components name lets me see how
the component gets the focus, how the edit field gets the focus and how the text is selected. The UI feels like waking
through water.

It looks like a known performance problem of UML diagrams 
on X server (like IZ 78574).  
Could you please:
- attach (several if possible) stack traces taken during the periods
  of slowness you described (Ctrl-\ in the command line 
  or kill -3 to the IDE process )
- run the IDE with -J-Dsun.java2d.pmoffscreen=false switch 
  (can be added in  <nb_install>/etc/netbeans.conf )
Comment 2 Viktor Lapitski 2007-08-03 23:44:21 UTC
it is either the known issue requiring -J-Dsun.java2d.pmoffscreen=false switch 
or something else that requires an additional info, at least a stack trace.  

"walking through water." is pretty much points to "pmoffscreen" issue.
This issue will go away once the diagram area redevelopment project 
completed (tentatively its completion is targeted to the next after 6.0 
release of NB)
