On 7.4 on two of my linux machines, the embedded goes black when I scroll (with the mouse wheel). The linux machines both run ubuntu, the one I am using nowt 12.04.3 and the other 13.04.

Both are running in 64 bit mode. The video cards are by nvidia in both cases. 
On this machine, it seems the problem is only visible when the css styles window is pinned, but of course this would be the mode where the embedded brwoser is most useful.

It looks like issue 236961. Does it happen only when scrolling or also after your run project/file? Could you please provide information about JDK? Thank you

Reporter, please run the attached app on your machine to see if the issue is reproducible in a plain Swing application, thanks.
Comment 3 homberghp 2013-10-29 14:29:27 UTC
Problem does not occur in sample application as per your request.

I tested with both the orignal (netbeans.org url) an with another url, the
one I used when reporting the problem the first time.

Intermittent. Sometimes the browser window starts black.

Tested on the ubuntu 12.04  LTS machine too. Same here, problem does not occur in standalone swing.
Ran it from the IDE as well as per command line as in
 '$ java -jar dist/browsertest.jar'
Comment 7 Vladimir Riha 2013-10-29 17:32:08 UTC
Thank you homberghp for the details.

I've tried it on Ubuntu 12.04 32b (32b JDK) and 13.10 64b (64b JDK) and cannot reproduce it, but both machines have only integrated Intel graphic cards

Maybe it is indeed related to the nvidia card.
The two machines I have tested it on are nvidia only.

I have a third machine with an intel graphics + nvidia graphics which normally
only uses the intel adapter. I will try on that one too, to see if that reveals anything useful. Give me a minute to install netbeans and repeat the tests.

I have tested on the intel/nvidia machine. In the energy save modus the problem does not occur.
Once I have my nvidia adapter active I will have another go.

btw: that machine runs a different jdk: 1.7.0_40-b43, 64 bit mode.

I have noted, that when I decouple the internal browser from the IDE (select chrome insetad of internal browser), but continue interacting with the internal browser the black flashes are gone. So it somehow related to the updates when the internal browser interacts with the IDE through the debug channel.
