1.12.1: Thumbnail view very slow after update

[Akovia]

XnView: xnviewmp 1.12.1-2 (+329 1.10) - 64bit
OS: Linux - 64bit

After updating system, it takes between 5-30 seconds to draw thumbs in a directory.

Effect: Program hangs

To reproduce:
1. Open xnviewmp

Actual behaviour (bug): Program hangs while loading thumbs

Expected behaviour: Draws thumbs fast as it always has.

The errors i see are:

Code: Select all

qt.multimedia.playbackengine.codec: "No HW decoder found"

I still have one of the nightlies installed and it was affected in the same way.

Edit: After being open for a while, it seems to get back to normal speed, but on first opening xnviewmp, it actually hangs the program enough that the colors fade out like it's about to get a kde system message that the program is not responding, but finally catches up.
