=== Work in progress === | |||
* Fixing up touch overhead at the beginning of pans (Some set of bugs) (kats) | |||
* TiledThebesLayer {{bug|739679}} (bgirard) - This will help remove buffer rotation overhead and will make it so we can resize the display port with less cost. | |||
* 16 bit drawing {{bug|733607}} (roc) | |||
=== Todo === | |||
==== Front end ==== | |||
* Slow down panning {{bug|742115}} | |||
* Adapt DisplayPort control for TiledThebesLayer {{bug|737510}} | |||
* Lower/Remove Viewport:Change observer overhead {{bug|742128}} | |||
* Round zoom level to avoid churning glyph cache? | |||
==== GFX ==== | |||
* Improve text drawing {{bug|742134}} (This needs root causing still) | |||
==== Layout ==== | |||
* Unnecessary work during image painting {{bug|733941}} | |||
* Avoid compositing basic layers (this doesn't show up much on profiles yet but is still a waste) {{bug|735303}} | |||
* ComputeVisibility slowness {{bug|735893}} | |||
* DisplayList construction {{bug|735898}} | |||
