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 *** Thumbnails in MEGAsync directories are now seemingly governed by Dolphin settings > General > Previews > Skip previews for remote files above: x MB. STEPS TO REPRODUCE 1. Have MEGAsync official Linux client installed, and configure a directory to sync. 2. Have some images in the directory. 3. Configure Dolphin settings > General > Previews > Skip previews for remote files above: x MB. Changes appear to reflect on-the-fly. OBSERVED RESULT Thumbnails in MEGAsync directories will turn off when the option is set to No previews, or will selectively turn on/off depending on max size configured in the option. EXPECTED RESULT Thumbnails in MEGAsync directories governed by "Skip previews for local files" option instead. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE neon 5.24 KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION This does not appear to be an original behavior, as I remember it used to not do that a few months prior. However I cannot pinpoint exact versions. I personally don't think it makes much sense for the option to also apply to MEGAsync directories, because MEGAsync app itself does not do remote mounting (which you could've done with Rclone), but instead keep local physical copies of all the files in the directories configured in the app.
