Created attachment 148348 [details] certain thumbnails are not generated, the files are not corrupt, i will see if i can get a video recorded of this SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. have a directory with lots of files (7000+ in my Pictures folder in my case) 2. choose program that uses kde file picker to upload/save file and go to said directory OBSERVED RESULT certain files will not have thumbnails generated, does not matter the file size, seems to be random. mouseover the images without thumbnails will generate them. EXPECTED RESULT all thumbnails should be generated SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 Kernel Version: 5.17.4-zen1-1-zen (64-bit) Graphics Platform: X11 Processors: 16 × AMD Ryzen 7 5800X 8-Core Processor Memory: 15.6 GiB of RAM Graphics Processor: AMD Radeon RX 580 Series ADDITIONAL INFORMATION All thumbnails are generated in Dolphin properly, only the upload/save dialogs have this problem for me. default dolphin thumbnail generation options too with no filesize restrictions.
I can confirm this. It ONLY happens in the file picker with folders of large amounts of images, as it doesn't seem to be a problem at all in Dolphin. Sometimes you can "nudge" it to generate more thumbnails by changing icon sizes, but it doesn't work most of the time, and often makes you lose your place. This is very annoying. Mousing over the thumbnail doesn't have any effect in my case.
Any movement on this? It's pretty annoying for artists and photographers. Is there anything users can provide to help fix this issue?
They could put together a bug bounty of more than $1,000. That would probably be enough to entice a developer capable of investigating and fixing the problem to do so. Or they could directly pool their money to hire a developer to fix it (which would probably cost more than $1,000). Or they could find a technical friend and convince that person to do it. Or they can learn programming skills and fix it themselves. Beyond that, I'm afraid it's just a waiting game.
Perhaps I should clarify: Is there any *information* a user can provide to help debug this issue? At least for future reference, are the specific kio operations logged anywhere, to find a particular point of failure?
I think a developer just needs to investigate it at this point.
Perhaps notably, this issues occurs regardless if the user is using an SSD or not, opposed to HDD.
