Lately I have been connecting sometimes to my computer at work, from home via Remote Desktop Connection (RDP). While everything is pretty much acceptable, I have noticed that Netbeans was so slow in repainting its windows, to the point of becoming unusable. With other IDEs and other software in general I never had a similar issue. If you are experiencing the same problem, here is how to fix it.
Go to the installation directory of your Netbeans (that would be on Windows probably under C:\Program Files\NetBeans 8.0), and then go to the etc folder and look for a file named netbeans.conf. Open this file in an editor and search for the text “noddraw” (with two ‘d’). You should probably see that this property has the value ‘true’ set to it:
Change the value of the property to ‘false’ and save the file. Then restart Netbeans. Repainting must be faster now. Good luck!
