Screen flickering (curvefever.com)

[RichardFreeman]

Hello,

first of all I want to thank you guys for developing this great extension, I really appreciate the effort!

Website: http://curvefever.com/play2.php
Problem: Screen flickers for about 2-3 seconds black/white on dismissing the NoScript options bar using the X to close it and on open the website.
Specs:
- Firefox 40.0.3
- Linux Mint 17.2 x64
- NoScript 2.6.9.36

Websites to allow or forbid on http://curvefever.com/play2.php: curvefever.com, 2mdn.net, google-analytics.com

Of course, curvefever.com is allowed. The latter two are forbid.
The flickering does NOT happen if all three websites are allowed.
Afair, the flickering does not happen with those two sites forbid if using Windows.

Question: Do I have to permanently allow all three websites to avoid flickering or is this a fixable issue?

Regards

Please check the Browser Console (Ctrl-Shift-J) next time the flickering happens, & check it when the flickering doesn't happen (all sites Allowed); and post both sets of output here.

You should never need to Allow either ga or 2mdn to make a site work, because NS provides surrogate script for those.

Hi,
thanks, the results are as follows:

flickering appeared on site refreshing:

flickering did not appear on site refreshing (aka all sites allowed):

The outputs do look similar to me. I see only minor differences in the ordering of method calls. All JS/PHP errors seem to appear in both cases.

Oh phooey, I was hoping the JS errors or console log output would be different.
Thanks though.

This comment of yours is interesting:

Is it the same machine? (Is one a VM & the other not?)

If it's at all different, what are the two machines' specs?

Hardware Acceleration apply in Linux?
If so, any change if you disable it in FF & test?

I'm not seeing 2mdn.com, nor any flickering.

On the other hand, I don't have Flash.

I have tested it again. Indeed, on Windows, there is no flickering.
Yes, it is the same machine. A dual-boot to be precise.

I have tested disabling/enabling hardware acceleration. It did not make any difference.

I'm not seeing 2mdn.com, nor any flickering.

Yea, well, the whole game is written in Flash, I guess. Disabling it is no option obviously.
