Big CPU-consumption of picture viewer
Hello all, is anyone experiencing problems with built-in picture viewer? My settings: Attachments are shown in a column, not minimized as a symbol in message header preview. When I double-click on a picture-attachment the built-in picture viewer opens and CPU-usage increases dramatically from less than 5 to over 50 percent. The amount of CPU consumption seems to correlate with the file size.

Re: Big CPU-consumption of picture viewer
Hello Roelof, hello Volker, indeed, it's the zoom level. I understand that it consumes CPU-power to resize a picture but from my point of view, resizing a picture is not an endless process and CPU-workload should go back to a normal level once resizing has finished. But I'll switch zoom factor to 1:1 too. Guess that will be enough. Over here the PC has a slightly different config.

On JPGs and GIFs in the 1 MB range it would momentarily increase to 10% or 12% and immediately drop.
