Slow qml animation on linux
I try to write a program for such a device "Uniq-POS 55.02":http://unisystem.kiev.ua/en/product/pos-tyerminaly/characteristics/pos-tyerminal-uniq-ps5502.html.
I plan to use it on Linux.
And all I test on precompiled Qt5.0.2
But faced with the following problem that occurs - under linux (I tried Ubuntu 12.4 and calculate linux (a descendant of Gentoo)) i see a very heavy load on the CPU and the slow implementation of the animation. As an example for testing I use the standard example - "interaction" and animation when I press the button takes a few seconds.
I tried Windows 7 - all works well.
I understand from the forums that the problem likely is in the support of OpenGL, but in linux I see the following:
glxinfo | grep direct:
direct rendering: Yes
(and the video card is recognized by lspci)
00:02.0 VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller (rev 02)
Can you please tell me which direction to move further
Everything is connected to the drivers from intel and opengl. And tunning systems.
After testing on pure gentoo linux performance equaled the windows 7 - the animation runs smoothly, although the CPU load. Do I right, that this is partially software rendering?
Does it make sense to try to rebuild without qt opengl or not (and, indeed, how it can be done)?
