Bug 39234

Thank you for your bug report/feature request.
Unfortunately this bug will never be fixed or the feature never
implemented. The bug report/feature request will be closed.

this is still the case in 3.1rc5, and would still be great to be fixed! ;-)

another observation:

when you have tabs open in konqueror that display local files (file:/),
and you switch from one tab to another, the icons flicker the same
way.
They should only be repainted when the protocol changes between tabs.

(KDE3.1.1 on Debian/unstable now) 
I have placed "New Tab" and "Close Current Tab" buttons on my toolbar. 
When I press one of these buttons, the toolbar flickers as described above, which in 
short means: 
We have _ugly_ toolbar flickering when: 
- you switch from "Tree View" to "Icon View" in filemanager mode 
- you swtich from one tab to another 
- when you add or close a tab 
 
it's really really UGLY :-( 

yes, definitely, 
this flickering is really ugly and makes the feeling of an unstable or slow system! 
please fix this for kde3.2 ! if this depends on QT-Bugfixes, then please talk to trolltech.. 
(i notice this bug since a long time already) 
 
thanks 

This case is about dynamically updated toolbar icons flickering as soon as they are 
dynamically updated eg. due to a kpart change. I suppose delaying the display of the 
newly updated icons instead updating them in real time could fix the flickering. 

Or I wonder konqueror checks if it has to change toolbar. Like in tab1 I have /home so using 
FileBrowsing profile in tab2 I have www.google.com so I use WebBrowsing profile. when I close 
tab2 it has to update toolbar too so it flickers. 
 
Makes sense? 

Last comment was about tab flickers sorry for interruption but we seem to have bug 58040 as a 
dup of this bug. 

Flickering is not just ugly. 
 
It indicates unneeded screen redraws. 
 
Unneeded screen redraws slow it down.

I think I managed to reduce the flicker in CVS head to the two increase/reduce size 
buttons only. They belong to the view and get removed when one view gets 
removed and added when the other view takes over. 
 
To get rid of the flicker there, the unplugging of actions should somehow be delayed 
till a new part is ready, when plugging new actions it should be checked whether 
the widgets from actions-to-be-unplugged can be reused. 

Subject: Re:  flickering toolbar buttons when switching iconsize

hm, a simple solution is, not to remove the bigger/smaller buttons, but
just to disable them... because, anyway, there is no need for more space in 
the toolbar, if the buttons are removed in the "text-(only)-view" Mode.
when i think about Internet Explorer, there is 1 Bottun for Bigger/Smaller 
Font in the toolbar (if manually added). but it stays there always, even if
the Internet-site is using "Style-sheets".
In my opinion, i don't think that many changings in the views are ergonomic, 
if there is only a little little thing changing.. it is the same the 
situation like: if i start kde, and every session the desktop-icons are 
sorted diffrently (of course, this is not the fact, but..)

another nice improvement could be, that the seperator of sybmols in the
toolbars would be representated by a vertical thin line. not just by a " " 
space.
thx

Hey all, 
I encourage you all to also vote for bug 58040 at: 
 
http://bugs.kde.org/show_bug.cgi?id=58040 
 
This bug is a similar one, but deals more with tabbed browsing and flicker when one 
switches between tabs.

It's the same issue, really. There's no point spreading the attention among several 
duplicate bugs describing the same symptom achieved through seemingly different 
way. 

Some other flicker things I notice: 
-When switching between pages, the scrollbar on the side flickers 
 
-The icon in the window title bar flickers (it shows the webpage icon or whatever it's 
called) 
 
-When going from no tabs to two tabs, there's a lot of flicker 
 

Mostly fixed.
