white window borders in fully horizontally stretched windows

[Evan Klitzke]

Binary package hint: compiz

I'm experiencing this bug on an Intel video chipset (using the "intel" driver).

Here's how to reproduce the bug:
1) Open up your favorite application in workspace 1.
2) Expand the right side of the window edge all the way to the edge of the screen.
3) Move the window a tiny bit to the right, so that the right edge is now in workspace 2.
4) Move to workspace 2, and repeat the previous steps, moving the right edge into workspace 3.
5) Repeat again...

At some point the window won't expand any further (for me, with 1024x768 resolution, this happens in workspace 3). Right at this point, when the window is as wide as you are allowed to make it, the window borders will turn white, all around the window. It looks like this is the area where shadows are supposed to be drawn around the window. If you make the window a little bit smaller, everything should go back to normal, with the borders drawn correctly.

Don't Do That. :)

Seriously, though, it's a limitation of your graphics hardware, not a compiz bug.

Same behavior on Radeon Mobility M7 (7500) on IBM Thinkpad T42. Happens on all workspaces, and on any application. Just maximize screen and you will have a white border.

This is not a hardware problem.. Cmon

How is this not a bug? The window content itself is drawn fine, the borders become white. If there is some weird limitation on window width, it should be simply enforced.

Attaching a video of what's (still, on Karmic) happening when making a window "too" wide.
