Windows 8 Window blinks on startup

 
Hi,

This is a great replacement for putty but why the window blinks on first open? It is very subtle but it is present. It is like the Window starts black, and then the contents spawn.

It is because the graphic controls netarang use? I see the same issue in other apps.

Program Ver. : Xshell 4

The blinking may look more obvious in slow machines. We are working on improving this issue. Although this is not a major issue for most users, we would like to make the experience more smooth and flicker-free.

Good to know.

The window fades in all black so even if the machine is very fast (mine is pretty normal: Athlon x4, 8gb ram, 1gb geforce 9600gt, win 8 x64), it will be noticeable. I feel it is something related with the alpha transparency function? Other windows like the settings don't blink at all.

Thanks for the answer.

We found out that this bug is related to the animation option in Windows. We will fix this issue in the future.

Meanwhile, to fix this problem, enable the Animate windows when minimizing and maximizing option (System > Advanced system settings > Performance settings)

Hi again, I switched to putty for a while and I am checking again xshell (because got bored again with putty limitations) and this blinking window issue still continues!

So I think since you will never fix this, I should take a look:

1) There is a 150 ms sleep (just lazy coding?) here:

2) Also why is the registry "FirstRun" readed in between the window is created and then, sleep and then updated?

So... you can read the registry key BEFORE creating the window, and try to avoid the sleep. For the moment I just will increase that thread sleep a couple of ms to avoid the flickering in Windows 8.1
