Thumbnails disappearing when browsing through files.

[discip]

As I'm using thumbnails I noticed that they disappear if you go to the next page and only come back after the drive was excited and re-entered.

It's something I have to check on the original firmware. Will come back with the results, I am sure it can be solved.

I remember having a similar issue with the original firmware.

If I found the right spot than this should be the fix:

The link above is about the file extension, not about thumbnails.

[discip]

Yes, but it seems to be related to this issue somehow as discussed here: https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/issues/2300#issuecomment-1003675156

OK. I will look into it.

[kisslorand]

The issue has been found, working on a fix for it.

[kisslorand]

It has been fixed, repository is updated with the fixes. Thank you!

[discip]

... Thank you!

Clearly I'm the one having to thank you! 😃👍

Will test as soon as I'm home again.

Unfortunately there was a print running up until now, which on the other hand proved the hesitation problem to be solved! 👍🏻 🎉

After flashing the latest firmware the previously described ISSUES are GONE!

Thank you so much!

May I ask if it makes sense to improve this browsing behavior even further without affecting performance?

I was thinking about storing the 'thumbnails-pages' after loading so that they don't have to be loaded individually each time the files are browsed.

[kisslorand]

There is no place to store them, they are loaded directly into the RAM of the display driver as the file is accessed.

Alright. Thanks for the clarification! 👍
