annoying indicator blink

[ahunter]

Here is one annoying bug of  LabVIEW?  Help me out！

The code is simple as shown below. The string indicator update it value every 100ms in the while loop.

The proble is that the indicator on the front panel will blink (or in other words, flash). This is very annoying.

1. Both LabVIEW 2010 and 2013  have the same behavior.

2. It occurs no matter it is modern, classic or system control. 

3. If add more control to the same string source, only one will blink.

4. The numeric indicator has the same problem.

Before worrying about that blink, take some general tutorials.  An infinite while loop isn't something you want to get into.  Controls aren't indicators and vice versa.  NEVER use the abort to stop your program.

Just a heads up, I'm not seeing a blink of any kind in 2013.

Yeah, I use "control " as "indicator" by mistake.

But, the blink or flash  is surely there.

The blink I said here is not  the "blink" the color-change behavior, which can be set through the property node.

It behaviors as some flash of the text within the indicator.

Here, one more indicator is added.

Run the code, and you'll find the two indicator behavior differently.

One blinks, the other works corrently.

I don't see any blinking or flashing either.

Maybe the problem is your computer. See if there is an update for your video driver.

What are your font settings? (your image looks different)

What is your OS?

[ahunter]

I had test it on 3 different PC and 3 virtual machine .

would you please run this contrast code?

That's strange. If I open it and look at the unsave changes, it say it got converted from a different platform. Could you be running 32bit windows 7?

That is a symbolic font and does not tell us anything. What are the font settings (and font size setting) of you windows  desktop theme?

Do you still have the same problem if you select all your indicators and switch to a defined font (e.g. 17pt Tahoma).

What is the language setting of your OS?
