description |
When using the XShape APIs*, windows that have a rectangular shape are treated like normal windows (they get a title bar and shadow) even if the rectangular region is much smaller than the window.
When a non-rectangular window changes its shape to be rectangular, it gains a shadow that remains even after changing its shape back to be non-rectangular.
Ideally there would always be a shadow that matches the shape of the window.
In the mean time, the correct behavior might be to remove the shadow whenever a shape is applied. If the application wishes to remove an applied shape, they could do something like:
XShapeCombineMask(d, w, ShapeBounding, 0, 0, None, ShapeSet);
Please let me know if you need any more details, or if I'm missing something. (Unfortunately, the ubuntu-bug tool wouldn't work when filing this bug).
* http://www.x.org/releases/current/doc/xextproto/shape.html |
[ Impact ]
Non-standard windows of a non-rectangular shape end up with rectangular shadows drawn behind them by Unity.
It is better to have no shadow at all for these windows rather than an incorrect rectangular shadow.
[ Test Case ]
C code for a test case is attached to this bug. It needs to be compiled and run to demonstrate the problem and solution.
[ Regression Potential ]
Any code change to the Unity desktop shell could introduce a new crash or hang.
A possible regression in this particular fix is a lack of shadows when expected, or a non-standard non-rectangular window still having a shadow as before.
[ Additional Info ]
The Unity SRU fix for Ubuntu 14.04 LTS was cherry-picked from Ubuntu 14.10 where it has been in production use for some time without regression. |
