Description
enter interactive mode and click on scissor to create a new needle.
I got in most case a black screen. Go back and click it again, then it shows correct content in most cases.

sorry, I totally misread. Somehow I assumed this would be a very old ticket but it was actually a very new one :-D

I saw this as well on my instance, all I had to do was to wait for optipng processes to finish (or at least for the one processing the image I was waiting for) and refresh the page/needle editor.

What I got in Firefox developer console:

I can reproduce two different issues:
- Sometimes there is a very long delay. This might lead to a timeout. In this case reloading the page helps of course.
But maybe it is just because the machine was very busy at that moment.
- Sometimes the generated image is just black. In this case reloading doesn't help of course. Looks like a bug in the backend. Maybe the screenshot was taken when qemu has already been stopped.

interactive mode is dashboard too? I guess you better define what dashboard is not

I already stated that there are actually 2 different issues. This comment is about the 2nd one.
The black screenshot might be caused by the stall handing turning the screen black: https://github.com/os-autoinst/os-autoinst/blob/master/consoles/VNC.pm#L834
To verify this, I could try to turn the screen to another color (eg. red) in this case. If the needle editor then shows a red screen, we know where it comes from.

good idea. just patch zluo's machine and let him test that.
Updated by mkittler about 7 years ago
I suppose changing the color isn't that easy. But the change https://github.com/os-autoinst/os-autoinst/commit/85e7ee7baef472c4771641e7d5a51da8278b0c34 by @coolo might fix the 2nd issue. So you can update os-autoinst and check whether the issue still occurs.
BTW: I guess the comment # return black image - screen turned off should be removed.
EDIT: It seems like the 2nd issue actually doesn't occur anymore. Since the issue only occurred sometimes, further testing is required to be sure.

The 2nd issue couldn't be reproduced anymore so I assume it is actually gone.
The first issue could be improved by reloading automatically and displaying a loading indication might be useful as well.

I hit this issue all the time, it's actually worse on a test machine I've got here (16GiB RAM, Intel Xeon E5-1620 (2x4 threads)) and it takes well over a minute sometimes until the .png is available.
