--- Comment #3 from David Edmundson <k...@davidedmundson.co.uk> ---
I don't want to have generic "it's sluggish" reports. As per that other thread
the hardware is struggling with GL QtQuick.
But in this case that hardware has highlighted a weak spot we should optimise
regardless.
RubberBand::RubberBand(QQuickItem *parent) : QQuickPaintedItem(parent)
We're uploading a new texture the size of the band every single mouse move.
Texture uploads are one of the slowest things we can do.
A few thoughts:
* Do we even want the QStyle theme on plasma? If not, we can just use a
Rectangle / FrameSVG
* If we do, we should render once and 9-tile it
