flicker

问题 I stumbled upon a problem I cant solve nor can I understand. I'm writing a simple 2D game using Java 1.8.0_31 with java.awt.Canvas on Ubuntu 14.04. The problem is that I get this unbearable flickering(an issue I never had on Windows), to make sure my code is not the problem I wrote a small test program with a moving circle...

问题 I am using an Android WebView to show some HTML content (a String with HTML tags to be precise) generated at runtime. The content has basically an HTML <table ...> showing various stuff and the rows of this table are generated by my program. The HTML content is loaded in my WebView by calling the loadDataWithBaseUrl() method. Now everytime I generate a new row, I create a new <tr></tr> and modify the HTML string to add the newly created row to the table. Obviously I have to recall the

问题 I have two functions that I want to happen at the same time. Function 1 is a window scrollTop and function2 is an absolute element hide (#elem1). These two functions take place immediately after an absolute element (#elem2) is placed on top of (#elem1). Running these functions at the same time executes as: elem1 scrolls top elem1 is hidden elem2 scrolls to top This causes an instant flicker, blink on ios and I want to avoid it. I would have expected that changing the order of the functions

When user re-sizes the dialog, some of the controls in the dialog should be re-positioned (not re-sized) . It also involves re-sizing of the image inside the dialog. As the re-sizing of image makes the whole process slow,

问题 I have a Java Applet that is flickering constantly for me every time the GUI is redrawn. Most people don't see the flickering. Others are able to run the applet without any problems at all but I am not. I am not sure if this is a problem with the way in which I am redrawing the UI or if this is a problem with my JRE or what. I've exhausted myself looking up other people's similar problems but I have not yet seen an answer that applies here. I have shortened the applet I am running down to a
