RC4: Strange Redrawing when switching thumbnail view

[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>

Yes happened sometimes, but i don't know why

I know of 2 similar problems but i guess i'll have to wait for RC5. Hopefully i'll remember them.

Yes, me too, at least one.

Create one txt file in the xnview dir. and use it for such bugs/problems, like me

Confirmed.

But do you have a method to reproduce it always??

[helmut]

Confirmed.

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.

Confirmed.

But do you have a method to reproduce it always??

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).

[Danny]

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

Yes, also with default settings.

Not fixed in v1.80.1.

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.
