"Hi! If clearing cache (in Global Settings) doesn't help"
Not helped, checked it.
"the thumbnail will show up if video filename does not include certain characters in your language, right?"
No, all thumbnails will not show up. This is because thumbnails will not be created in situation when username has this character in name. So can't be shown as missing in skybox app data directory.
The issue is during creating thumbnails for videos - app data for thumbnails is empty when I'm using user with special characters.
Workaround for me is:
- login to windows with user without special characters
- open skybox with this user and load videos
- go to this user skybox app data, copy all thumbnails with configs to app data of user with special character. Then thumbnails are normally shown when I open skybox by user with special character.
So it looks that issue is not with cache or showing thumbnails. Just creating in situation like I described above. Thanks.
For me problematic character is: ł
Represented by unicode as: U+0142
