RC4: Strange Redrawing when switching thumbnail view

Post by helmut »

There's some strange flickering and redrawing when switching in between various thumbnail views.

To reproduce:

1.) In XnView browse a folder with many images (e. 100 images - the more the better).
2.) Press F9 several times to switch between the various types of views for files (Thumbnails, Thumbnails & Details, ...).
-> When switching to "Thumbnails", there is some strange redrawing. One can see the thumbnails, already, but then they are rearranged. This looks odd / wrong.

XnView 1.80 <x>

For me this happens always. And the more images the more obvious it gets. Active/inactive cache has no influence.

The problem can be seen in RC3 and RC4, in RC2 this works fine.

Yes, also with default settings.

I can confirm that with Win XP / SP2.
The flickering occurs when I return to the initial layout after switching through the whole list of thumbnail views (the last F9).

Yeah, well... The program is probably just arranging/loading the thumbnails one by one. Nothing to worry about IMO.

The strange redraw can also occur when file is downloaded into same directory (auto-refresh on). Like helmut, I only see problem in directory of 100+ thumbnails. I don't see the redraw with 9 thumbnails.
