Bug 290246 – dev-util/qt-creator-1.2.90 runs with 100% process-usage on one core

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michael Mair-Keimberger (mm1ke) 2009-10-23 14:25:13 UTC]

Qt-Creator runs at 100% on one core after starting it. Afterwards it cannot be closed proper. The gui seems to terminate normally, but there is still a process in the background which still needs 100% of one core.

Reproducible: Always

Steps to Reproduce:
1. emerge qt-creator-1.2.90
2. start it
3. look at (h)top for the process-usage

Actual Results:  
Actually i don't think qt-creator needs 100% of one core all the time ;)

After downgrading and upgrading again the problem seems to be gone :)
Bug can be closed. It works now :)
