Diagonal arrows in workspace switcher are jagged while horizontal/vertical arrows are clean

[Eviatar]

When using the keyboard shortcuts to switch workspaces, and a diagonal move is performed (from top left to bottom right, for example) the arrow icon looks pixelated and jaggy wheras the up-down and left-right arrows are clean.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

I can say that, yes it is reproducible. To recreate it you just have to switch between two diagonally placed workplaces.

[Andrea Azzarone (azzar1)]

I can repdoduce this bug! More informations: set the keyboard binding to go to specific viewport in Viewport switcher (ccsm).

[Christopher Kyle Horton (christhehorton)]

@Andrea Azzarone: I can reproduce this by just using the Ctrl+Alt+Arrow Key keyboard shortcut and pressing a vertical and horizontal arrow key at the same time to switch diagonally. No modification via ccsm is necessary.

This bug is still present in Oneiric Beta 1.

[Christopher Kyle Horton (christhehorton)]

Still present in Precise Alpha 1.

[Christopher Kyle Horton (christhehorton)]

Still in Trusty, too.

Just a guess as to where to check...but in compiz, maybe the problem is in /plugins/wall/src/wall.cpp? Maybe in the

void
WallScreen::drawCairoTextureOnScreen (const GLMatrix &transform)

or

void
WallScreen::drawArrow ()

functions?
