QT Creator slow performance on ubuntu
-
Hmm, for me it is not the case now, but it is still my favourite. However the performance problem seems to happen when I press the enter key and it needs to create a new line: it would become very slugish when a file exceeds 500 lines of code (I don't have a lot of includes: common iostream, vector, string and map). Maybe it is the rendering that is bad and something is wrong with QT 4.7. Please note that I am using a very simple theme with no compositing and metacity.
My system is:
Intel Core2 Duo 2GHz, 2Gb RAM
Nvidia 8400G 128M RAM and 260.19.06 driver.So can you please tell me how to make QT Creator usuable again ?
Thanks

What version of Qt is that? If that's 4.7.0 try 4.7.1.
-
I'm using the Qt Creator on a Ubuntu virtual machine and it is not slow at all! I'm using the Qt SDK that means Qt 4.7.0 but the Qt Creator RC!
-
I am using QT 4.7; I have tried QT Creator 2.1 RC, seems to be a little better but not noticeably better!
Are there any performance enhancement with QT 4.7.1 ?

I have used Qt creator on ubuntu 9 and did not notice any problems.
-
farakon: Please update to Qt 4.7.1. There are known performance issues with Qt 4.7 (see the release notes).

To those having the same problem, I restart QT creator with:
qtcreator -graphicssystem raster
QT creator becomes as responsive as it was before. So hope it helps.
I wonder why the raster is faster than the native system, I have read the blog, so the question why not make it by default ?

Thanks @farakon, it's just that i needed. QtCreator was very slow when i moved the cursor with the keyboard, it leave a "shadow". Now it run fine.
-
Thanks @farakon as well. I was having the same problem (text cursor not very responsive) and it was solved with the -graphicssystem raster switch.
