[digiKam-users] Missing portion of image

[digikam at 911networks.com]

DK 6.3.0 appimage on Manjaro-KDE

I'm browsing a medium size folder within DK. It has been imported,
everything went ok. But...

As I browse the folder by paging up/down, often either the image
preview is missing or just a section of the image preview is
displayed. 

The imagename is there for all images including the one not showing the
preview.

If I move the cursor over the missing preview, then the preview shows up in
full. All of these images are either CR2 (Canon) or RAF (Fuji)

I tried to do some screen capture with Spectacle, but as soon as I
click on Spectacle, then rest of the previews appears.

1. Is there something I could do to, it's annoying
2. Am I doing something wrong and should browse differently?

My hardware should be good enough: AMD fx-8350 (8 cores), 12Gb RAM,
No swap happening (1.1Gb memory used with DK open), Radeon 570/8Gb RAM
