Version: (using Devel) OS: Linux Installed from: Compiled sources at certain window widths dolphin doesn't appear to know wither to show n images in a row or n+1 and constantly switches back and forth between the two counts. this results in flickering until the window size is changed. the easiest way of replicating this is to slowly adjust the width of the main window but the flickering can also be triggered when moving from one folder to the other when mix of images sizes changes the current 4.2rc1 (as supplied by opensuse) doesn't exhibit this.
Thanks for the report, but I'm a little bit confused as the code responsible for this has not changed for RC1 and the current SVN (or 4.2 latest) and I cannot reproduce it. Can you tell us which style you use (Oxygen?). During the beta2 phase we had a problem when using other styles...
I could still trigger this this evening. The theme used didn't make any difference and I couldn't trigger it using the same folder contents under RC1. Most folders are fine it just seems to happen when a change in the width of a window results in an extra row of previews. If this extra row can no longer fit in the vertical height the drawing of a vertical scroll bar starts the flicker as the scroll bar is first draw then un-drawn repeatedly.

Comment on attachment 31260 [details] The critical situation This shows the situation where the bug occures. when i decrese the window size just a bit, i see the flickering.
I could reproduce the issue when using Qt 4.5 instead of Qt 4.4. I applied a fix to trunk and have backported it to KDE 4.2.1. Did you use Qt 4.5? If yes, then this issue can be closed as FIXED...
I was/am using qt 4.5 and can no longer trigger it with current trunk so marking as fixed as suggested.
