Windows 7 Trasparency issue (yes, i'm still using W7 on some machines) #358

TrafficMonitor v1.78 (x64)

Enabling Transparency in Windows7 seems to cause some weird behaviour as you can see in the following images:

Transparency ON, the task bar widget looks fine.
Transparency ON, but a window dragged lower than the task bar. Will interfere with TrafficMonitor, causing a weird look because of the transparent "cutout" in the taskbar.
Transparency OFF - I'd expect the background of the taskbar notification to be as set in color settings. However, it looks bright gray and the text is all white. I believe this is a bug and it should be fixed.

Worth mention that my windows has this visual style alteration applied: http://www.windowsxlive.net/windows-10-transformation-pack/

I hope this helps to bring up a fix.

Wondering if this issue has been considered or completely ignored...

~~since you're using custom theme, i don't think the problem come from TrafficMonitor.~~

after doing some test i found that this is happen if you disable transparency and set color intensity to 0

try set color intensity to 100 if you disable transparency

Thanks for looking into it. From what I could see, the issue may be with how the taskbar and your app interact. It looks like the colored background for Traffic Monitor has a different Z-value than the text. So, whilst the text is on top of everything, the colour goes behind windows that are being dragged under the taskbar.

As you will be able to see in the attached screenshot, I made Traffic Monitor's Bg Green:

with transparency DISABLED the window received a white milky overlay (frosted) and that white cannot be altered in program's settings.
with transparency ENABLED, the frosted aspect goes away, but now you can see the corner of the window that was moved under the taskbar. Also, the window was covering the green background instead of the background being on top of the window and just under the Traffic Monitor data display.

My thought is that it could prove useful to look into how the different layers are stacked in relation to other elements.

Thanks for your feedback. Actually I have noticed this problem in Windows 7. But now I have no idea to fix this problem. There is a "Background transparent" option beside "Background color", but you can see that it is disabled in Windows7. Because I found that it doesn't word in Windows7. In Windows8/10, this option works. If you are using TrafficMonitor in Windows7, it is recommend to set the background color in TrafficMonitor to pure black (RGB: 0, 0, 0), and try to increase the color intensity in Personalization in Windows 7.
