--- Comment #1 from Piotr Kołaczkowski <pkola...@gmail.com> ---
Today I noticed another interesting thing.
The performance depends on the size of the Impress main window. If I keep it
maximized (2560x1600), the performance is terrible like described. If I keep it
much smaller, e.g. 1/2 of the full size - it gets acceptable. Still far from
responsive, but at least usable.
This let me come to an idea of checking what top shows during the process of
moving the table. It turned out, Xorg is taking 99% of CPU (when moving table
in LO) while LO itself is fine with only about 5-15%.
So I guess LO must be doing some heavy refreshing or repainting or some other
heavy calls to the graphics pipeline, even though the operation of
moving/selecting 2D objects is extremely simple. My slides are nothing fancy,
no heavy images, no videos, no embedded objects, mostly academic-style black
text on white and a few small tables. Even if you needed to repaint the whole
slide in the loop, performance for that kind of complexity should be in
thousands FPS, not 0.2 FPS.
BTW: I'm neither noticing any performance problems like that with other
applications that involve dragging 2D objects or even drawing lots of moving
elements games. Ubuntu Unity flies on this hardware and both 2D and 3D
acceleration is awesome.
