Description Paul-Sebastian Manole 2013-03-29 10:05:40 UTC

KMail uses 90% CPU when hovering over some of the items in the Tools menu. The items that seem to animated on hover. No the items that seem to hover instantly. All other menus don't seem to produce this. Kontact/KMail 4.9.5.

Opening KMail through Kontact makes it worse.

Reproducible: Always

Steps to Reproduce:
1. Open KMail or Kontact
2. Hover over items in the Tools menu
3. Watch top for KMail CPU usage
Actual Results:  
KMail uses 80-90% CPU

Expected Results:  
KMail should not use more CPU than when hovering over items in other menus (10-15%).

Running Kubuntu stable. Fresh install. AMD graphics card. Open source drivers. Sony Vaio VPCEB2S1E laptop.

Confirmed, something is very wrong in that menu. Note this also causes a noticeable UI delay when hovering over items and when opening the menu.

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
