Kodi graphics failure

I use Kodi now for a long time. Kodi 16 runs perfect on my Windows 10 HTPC.
I updated now to Kodi 17, no hardware change, clean system.

Now I have problems since the update.
First I noticed that in the category pictures. When I see my photos, the kodi gui is hanging and I have only seen the distorted photo.

This condition I have now also in the main view experienced. I have not used kodi for an hour, the screen has been dimmed and I have had to wake up kodi again. And here is the same problem.
In the log are also corresponding error messages to see. Someone has a hint?

Code:
23:57:12.366 T:2916   ERROR: CBaseTexture::Allocate - Could not allocate 8294400 bytes. Out of memory.
23:57:12.367 T:2916   ERROR: CImageLoader::DoWork - Direct texture file loading failed for special://masterprofile/Thumbnails/0/0b760f4b.jpg

I have in my HTPC 16GB Ram, the hard drive is a ssd with plenty of space.
