Description sorinn 2014-03-21 10:23:54 UTC
Product Version = NetBeans IDE 8.0 (Build 201403101706)
Operating System = Linux version 3.11.0-18-generic running on i386
Java; VM; Vendor = 1.8.0
Runtime = Java HotSpot(TM) Client VM 25.0-b70

Netbeans 8 (HTML and PHP version) come unusable for webdevelopers who want a quick check of their scripts

Usually webdevelopers keep few windows / browsers opened at the same time - so the embedded webkit preview is used for the small quick checks 

Not always you need to check the whole project in a browser window - therefore the embedded preview come as an important tool for us. 

in 7.4 this was fixed - but in 8.0 this bug is back - so we have to stick with 7.4 until is fixed. 

I've do my research and I discovered that this bug is desctibed here :

..hope it helps

the workaround presented here is made for peoples using jQuery lib 

if you do not use jQuery on your project, use this code at the end of your file you want to check : 


        function hideNetbeansGlassPane()
        setTimeout(hideNetbeansGlassPane, 500);

I'm on Linux with Nvidia too, but I think this is not Nvidia related. The problem is caused by the canvas added at the end of the previewed html.

Currently I'm using a quick workaround, I' just added this code:

~~~~ html
        function hideNetbeansGlassPane() {
        setTimeout(hideNetbeansGlassPane, 500);

at the end of HTML generated by the app I'm working on. It's basically about hiding `<canvas id="netbeans_glasspane" ...` which is added at the end of generated HTML (You can see this right click on browser -> dump document).
Canvas needs to be destroyed/hidden after a small delay. Directly on `.ready` without a delay will not work as expected.

Why are you opening another issue with the same problem if you found the older one? Isn't this a dupl. of the issue 236961 ? Could you instead add informationVidean to that issue (e.g. if you have nVidia graphic card)? 

Removing the canvas breaks some web inspection features and NetBeans uses canvas to highlight elements on page.
