Mac OS X 10.6.2 (32bit kernel) running on MacBookPro (Intel, 64bit capable Core2 Duo)
Qt SDK 4.6.0 RC (1), Qt SDK 4.6.0 (final)
Description
Hi!
Today I noticed my laptop getting unusually hot and when I looked, I found Assistant from the new Qt 4.6.0 RC SDK uses about 130% CPU resources.
I attached samples from ActivityManager.
I can consistently reproduce this (even after restarts) as follows:
- Open qtdemo via Spotlight
- go to "Concurrent Programming"
- go to "Run Function" (these two could possibly be arbitrary)
- click on "Documentation" which launches Assistant
- browse in Assistant (i went to the QtConcurrent section)
- Quit qtdemo now
-> The CPU usage of Assistant explodes
This issue should be fixed before release of 4.6.0, as it is not uncommon to reproduce and has impact on system performance.
If i can assist in the tracking of the issue further, please let me know.
Thanks!
