Panel color showing through browser

Even though panel is set to autohide, the blue color (or any other) permeates through the web browser:

In this case, panel is set to autohide at top of monitor but it does it at bottom too.
In fact, it also shows through wallpaper as well.

that seems to be a feature on a lot of panels that when they autohide there's a small preview. that is not abnormal. Not sure if it can be disabled or not. What panel are you using, default xfce4? maybe settings might have something

You were fast!

Even wallpaper has same issue.
Now to find the culprit...

it's normal. please tell me what panel u r using for top.

Setting panel (which i moved from bottom to top) background color to black makes it much better.

please,please answer my question. which panel are you using? docky? lxpanel? xfce4-panel (default for chalet)?

Sorry. Chalet default.

ok sorry for late reply was eating breakfast

so I tried it and I get same result. Unfortunately there's nothing you can do on xfce4-panel to fix that (chalet os default).

Not a problem friend, i shouldn't haven't been posting that early.

that's not a problem at all
