[gentoo-user] qt-creator (and others) too slow
Hello, all. Interesting thing: running QtCreator in another machine with no KDE (using WindowMaker) it runs as expected. On another machine, the main one I use, with KDE, QtCreator (and other program, as stated on the subject) eats CPU resources and behaves real slow. On this KDE machine, connecting to the first one via ssh and running its QtCreator, it starts to behave like the original one from this machine. Starting QtCreator from a terminal, it says: libEGL warning: DRI2: failed to authenticate Starting QtCreator directly on that other machine, that warning does not show up. Any hints? Both machines run the latest stable versions of QtCreator, Qt:4 and Qt:5 Thanks! Francisco

Are you running any special kernel configuration like the CK patches?

I have noticed some slowness when baloo is running, as Fernando mentioned. I turned off file indexing, which does not seem to have actually done anything. Anyways, other than that, KDE for me runs very smoothly. Most of the time, even when baloo is running full out, KDE itself is very responsive. Qt Creator currently segfaults when I try to create a new project or open a project, but other than that is generally responsive. Which version of Qt Creator are you running? Alec

I just installed stable KDE 5 on unstable Qt 5, as tiling window managers are not great all the time. I have not noticed any problems so far related to rendering. I can test this in a little while, but I'm busy working on some stuff right now while logged in to i3. Alec
[gentoo-user] qt-creator (and others) too slow
Hi, all, Just upgraded to KDE 5, Qt 5 (as full as possible) and now QtCreator frequently uses almost full CPU, a quad-core i5-4430. Any change on the IDE, even just passing the mouse cursor over elements of an opened source code file, makes the CPU consuption to the high tops. It also happened when I tried some widgets using plasmashell, like the analog clock and the Desktop widget. The process "plasmashell" eat up all available CPU cicles. Could it be something related to more deep details inside Qt basis? Turns out to find funny QtCreator's description on KDE menu: "Lightweight IDE for C++ ...". Any hints to find out what is happening will be highly appreciated. Best regards, Francisco
