[Development] Quick in Qt 5 is sluggish and other observations

[Ariel Molina R.]

Hi,

I just downloaded Qt 5 from git, and compiled using the instructions
found in the README

For a stable build of Qt5:

   ./init-repository
   ./configure -prefix $PWD/qtbase -opensource
   make -j4

First observation:
It did not install qtdeclarative, i had to manually go in and make install

Second observation:
After installing i tried the QML examples/particles from the git clone
dir (as they were not installed either) using the example launcher.
Observartions:

1. Low framerate, after a while i disabled KDE compositing and got
smooth framerate.
2. Low framerate when hovering the mouse over the qmlscene window
3. Low framerate when pressing keys, any key. Just let any key pressed
and framerate drops to a unusable rate.

Third observation:
Cannot "design" anything with QtQuick 2.0, because the designer complains about:

The executable of the QML Puppet process:
<path>/qmlpuppet cannot be found.
Blablabla...
