555285 - Direct2D surface is recreated a lot

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[Jeff Muizelaar [:jrmuizel]]

Call stacks like the following cause us to recreate our d2d surface. I don't think we want to be doing this.

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

I agree.  I believe that the surface provided by GetThebesSurface is only used for measuring text; do we even need it?

Should this bug still be open?
