Not fixed my situation either, still get names but no thumbnails.

Difficult to reproduce the problem...

How do you two scroll? Scroll bar, Wheel, or PageUp/Down?

Disk cache for thumbnails is ON but thumbnails are not yet all created, right?
Do you also get the problem with cache OFF?

I have cache OFF, very rarely use caching since I look at many different and changing directories, so caching doesn't help.

Scroll with keys usually but mouse on scroll bar has the same effect.

What appears to happen is this:
Thumbnails are being created, from the top of the list, so scroll down quickly to a point in the list and thumbnail generation starts from that point.
When some thumbnails have been created, but not the full screen, scroll quickly up to another point in the list that already has thumbnails created.
Thumbnails again start being created from the top of the screen. Part way through the screen, I think at the same screen position that the thumbnail was being created before scrolling to the current position, thumbnails that are already displayed, start being removed.

Hope that makes sense!!

i scroll using the mouse wheel.

i could reproduce it with cache disabled (like Gandolf explained), but it was much harder to do it, and only 2 thumbs were missing.
with cache enabled i can reproduce it almost every time, and usually there's at least one full line of missings thumbs and/or misplaced icons.

OK, thanks both.

I managed to created the "missings thumbs" bug (but never any misplaced icons) very rarely using the wheel. And I could fix it I think. Check next version...

There is no unicode bug -- all works perfectly.

EDIT, after countless hours of testing different scenarios, I narrowed it down to a character " メ " breaking it

make a new folder with this character " メ " then thumbs won't generate for movies

(ignore the $ folder since that was from dragging a folder from the recycle bin)

Works alright.

weird...oh well not a big deal, i don't use thumbs much anyways,

and to get proper Japanese support you would need to change a bunch of windows settings and reboot, and i don't think your willing to do that, might even be the way windows 7 / vista handles that character.

Code: Select all

v8.10.0021.....
    ! Thumbnails: Display glitch when scrolling fast while fresh thumbs
      are being created. Fix #2.

Still not fixed my situation, I get names but no thumbnails.

Then it's probably something in your configuration that's different from mine.

Once you resize the Window (or the list via splitter) the missing thumbnails are painted, right?

but it seems to have fixed mine.

i couldn't make xy display any misplaced icons or missing thumbnails.
i tested various thumbnail sizes, with the cache enabled and disabled.

I also encountered this bug somehow, but have not yet found the consistent repro steps... I only encountered this bug while the folder is caching and is being scrolled.

Don, I collected two threads that may help you to investigate:
1. Quickly scroll and suddenly stop in the middle section, assume there are 40 files here from left-top to right-bottom. A display order example that caused the bug may like this: 1st - 5th, display thumbs, ?th - 11th, display blanks, 6th - 40th, take over the priority and continue to display thumbs, 12th - 40th, display the remains of blanks. So, the final result is, 12th - 40th files were displayed as blanks instead of their thumbs.
2. In rare cases, while dragging the scroll handler, the handler will jump to the last place the thumb is being displayed, and then jump back to the cursor place, and repeat until something unknown is done in that place or you release the handler and re-drag.
I'm not talking about the top align with visible area joggling, but it may be caused by that, XYplorer was trying to align a row very far away from the visible area and something wrong (why repeat) with that row.
BTW, Don, could you please consider to change the scroll handler position adjustment behavior? This makes the scrolling operation not smooth.

Thanks. I'm scrolling like mad but cannot produce any problems. I have to classify this case and rare and exceptional and will move on to other tasks for now.
