Version: 3.1.1 (using KDE 4.1.1) OS: Linux Installed from: Debian testing/unstable Packages Steps to reproduce: 1) Make the open documents list on the sidebar visible. 2) Open a few documents 3) Select one of them and click "close" on the toolbar. 4) All documents are now hidden from the documents list and are restored only when you mouseover them. I think this started to happen when I upgraded from Qt 4.4.0 to 4.4.1, so this could be some sort of Qt bug, but I haven't been able to reproduce it with any other QListView.

Here using: Qt: 4.4.3 + qt-copy-patches-889120 KDE: 4.2.60 (KDE 4.2.60 (KDE 4.3 >= 20090106)) kdelibs svn rev. 908156 / kdebase svn rev. 908156 kdesdk svn rev. 905676 on ArchLinux x86_64 - Kernel 2.6.27.10 I can reproduce the bug Detailed Steps - Open Kate - Open a bunch of files Control+W or "Close" icon on toolbar works OK (the files are closed and the list flickers but it's still there) - Now, reopen all the same files Control+W or "Close" icon on toolbar close the file, but the list is blank until you mouse over it and it's repainted.
I can also reproduce this bug Kate Version 3.1.96 KDE 4.1.96 (KDE 4.1.96 (KDE 4.2 RC1)) ) OpenSuSE KDE4 Factory Repository for 11.1 It seems this problem appears *only* when opening a specific number of documents (or even more). I 've tryed it with 4 or 5 -> all seems ok, with ~12 docs the document list isn't beeing redrawed when closing a document.
Confirmed, using: 3.1.96 (KDE 4.1.96 (KDE 4.1.96 (KDE 4.2 RC1)) "release 78.1", KDE:KDE4:Factory:Desktop / openSUSE_11.0) It does not always happen. I see the bug in my kate now, but when I open a new kate instance it works perfectly, even with the same amount of files.

Here using: Qt: 4.5.1 (qt-copy 958974) KDE: 4.2.71 (KDE 4.2.71 (KDE 4.3 >= 20090428)) kdelibs svn rev. 960693 / kdebase svn rev. 960693 on ArchLinux i686 - Kernel 2.6.29.1 Now, when closing a document, the document list flickers but all the elements are repainted properly. The user doesn't need to mousehover them
Bug is still present in 4.2.2 using openSuSE 11.1 with Qt 4.4.3
This bug is fixed in 4.3.1 in my test (actually, since 4.3.0, I think).
Indeed, I cannot reproduce anymore. I can confirm though that it still flickers a bit, as Dario said in comment 8
I don't even see any flicker now. Normal laptop, desktop compositing enabled, in case that matters.
