Launcher, Window management - Desktop Background Bleeds through next to Launcher

[Jason Warner]

If I have a colorful background and have a dark webpage open (works with any dark maximized window...think Sublime Text) I see the desktop background bleed through next to the launcher and maximized window (see screenshot).

------------------------------------
Desired Resolution:

- When the Launcher is locked out and a window is maximised, the window border should be flush with the Launcher. At the moment there is a 1px background bleed through, see attached screenshot.

Confirmed. As far as I know, the bright line is part of the launcher itself. It is designed to brighten what's behind it (the wallpaper).

We could either remove this 1-pixel-wide line, or just change the underlying X window to ensure maximized applications overlap the bright line by 1 pixel.

It sounds like the latter is planned, but be warned that doing so could cause a regression in desktop performance, as the maximized window would be damaging the launcher region, triggering slow and expensive redraws.

The safer solution is to just remove the bright border from the launcher.

From a design POV, the preferred fix is to "just change the underlying X window to ensure maximized applications overlap the bright line by 1 pixel."

Removing the 1-pixel-wide line will in some cases cause a visual regression.

WARNING:

Implementing the fix suggested in comment #3 will cause damage to be propagated from the maximized window to the launcher, triggering a regression of bug 988079, which is very important.

Do not implement this fix until you have a plan for avoiding this problem.

Actually I could be wrong, thanks to bug 1036519. If that gets fixed though, comment #4 definitely applies.
