Description Martin Kampas 2011-01-23 11:54:48 UTC 
Version:           4.6.0 (using KDE 4.5.95) 
OS:                Linux

IIRC, it used to be possible to close other tab "silently" using middle click. Now the behavior changed and middle-clicking on a tab first make it visible, then close. As a result, the tab left to the closed tab becomes the visible one.

Reproducible: Always

Steps to Reproduce:
1. Open three tabs
2. Select the first tab
3. Middle-click on the third tab to close it

Actual Results:  
The third tab becomes the visible one for a while, then it is closed and at the end the second tab becomes the visible one.

Expected Results:  
The third tab should disappear silently and the first tab should remain the visible one.

OS: Linux (x86_64) release 2.6.36-gentoo-r5
Compiler: x86_64-pc-linux-gnu-gcc
Comment 1 Burkhard Lück 2011-05-12 11:41:24 UTC 
Checked this issue with Kubuntu 10.10 (kde 4.6.2) and master/branch 4.6 compiled from sources.

The third tab disappears silently and the first tab remains the visible one, this is the result you expected.

Please try again with an up to date kde, thanks.
Comment 2 Martin Kampas 2011-05-13 06:42:35 UTC 
Checked with KDE 4.6.2 (on Gentoo), the behavior is still the same.

I noticed there is a (new?) option in General section "Activate previously used tab when closing the current tab" - with this enabled, it *partially* works: at the end the first tab is the visible one, but it still brings the third tab info foreground for a while.

This causes unnecesary redrawing, reswapping memory if the tab has not been used for some time etc. and as a result it takes a noticeable amount of time to close a background tab (2 cores @1600MHz, 3.3GB RAM in my case).
Comment 3 Dawit Alemayehu 2011-06-29 03:43:34 UTC 
confirmed. Use the RMB and selected close tab when the context menu shows up does not show the same side effect.

Git commit f8309bec7316e6bb6ff90b76cc99c798ff045f6f by Dawit Alemayehu.

Pushed by adawit into branch 'KDE/4.9'.

If the "Middle click on tab to close" option is checked, do not select the
tab when the MMB is clicked on it. Instead simply close the tab.
