Alex,

Currently we have no access to a dual monitor setup running XP natively. As I said, I am not sure that XP is the only component needed in order to repeat the problem. I am fully aware and respect that this kind of situations are really annoying. However, currently we haven't received any other complaint about slow editor response nor bad scrolling performance with version 8.0. Are you able to repeat the behavior on other machines with similar configuration (OS, dual monitor, etc)?

Also, is the sluggish performance visible only in the editor or also in other text fields?

Regards

Roger

Roger..

Yes, it it frustrating, especially when I dont see this issue when I use other apps, such as Toad, SQL Server Management Studio, Word or even IE.. I even put them (apps) side by side to see if the performance takes a toll on all apps, but as soon as I move my mouse away from dbVis onto other app's space, the other app performs normally.. As soon as I move back to dbVis, same issue...
Just to check, I installed *7.5 (*version that has the old sql editor) -- and the issue is NOT observed.

It affects all of dbVis GUI, menus, typing, scrolling ... And again, the issue disappears after I do the 'work-around' mentioned earlier... Thats whats interesting.....

HOWEVER, as I was typing this response, I decided to try this flag -Dsun.java2d.d3d=false . Restarted dbVis (8.5) and the issue is gone... Tried the same w/o the flag by turned off Direct3D in dxdiag tool --- the issue is gone.. ..
..... So, is 8.# is using Direct3D differently than 7.5 ?

Hi Alex,

The main difference between the apps you've tested with and DbVisualizer is that DbVisualizer is Java based while the others are native.

It was great to hear the issue is gone when you disable Direct3D.

The use of d3d is hidden completely in Java and possibly 3:rd party components that is used in DbVisualizer. There is no change in our codebase regarding that in version 8. However, the main difference in v8 compared with previous versions is that we are now using a new editor component which may explain why you experience the changed behavior. I will check with the vendor if they are aware of any problems and if the specifically use d3d based code.

Regards

Roger

I was having the exact same problem. (Ubuntu 11.10, DbVisualiser 8.07)

The SQL editor has a 1-2 second delay for key presses, once the editor has been used once or twice.

I inserted -Dsun.java2d.d3d=false into the shell script and everything fine now.

Just a me too - comment, ran into this when upgrading to 64-bit Ubuntu LTS with nvidia native driver and OpenJDK and running Dbvis 9 series.

The setting mentioned above fixed it.

However isn't the file dbvis.vmoptions a preferrable place for these kind of settings?

Jonas,

You are correct in that the dbvis.vmoptions file is the recommended place to set JVM properties.

Still correcting myself as the response grew again after some time.

Actually sun.java2d.d3d is valid only on Windows platforms.

However the setting sun.java2d.opengl=true fixes the slow response.

Still still updating myself.

The opengl setting has no effect at all, only the fact, that the application is restarted.

Still with 64-bit ubuntu 12.04 I can reproduce the following behaviour, with both Sun Java and OpenJDK with version 9.0.4 and also 8.0.11

1. Open a new tab

Typing speed is not an issue

2. Select some text

Typing speed is down to a crawl, characters written flush out once a second, about

Close the tab and opening a new restores the speed. Other open tabs are unaffected.

Other java ui tools eg Eclipse, jedit are not affected.

Jonas,

Are you using a plain install of Ubuntu 12.04 or are there any add-on features enabled such as window manager, themes, etc?

I just tried 12.04 LTS and Java 1.7.0_07 and the typing speed in the editor is constant for me.

In case it helps, I can confirm the same behavior.

I'm running Ubuntu 13.04 now but the same issue was happening with 12.10.
