When trying to navigate files and folders in any directory with the Orca screen reader turned on, there is a consistent lag (a second or more) that impedes quick and efficient navigation. STEPS TO REPRODUCE 1. Turn the screen reader on. 2. Open Dolphin. 3. Try to navigate files and folders with the left and right arrows OBSERVED RESULT There is a consistent lag that does not allow a smooth navigation. EXPECTED RESULT This lag should not be present at all. Operating System: Arch Linux KDE Plasma Version: 6.0.0 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.7.6-arch1-2 (64-bit) Graphics Platform: X11, although this happens on Wayland as well. Processors: 8 × AMD Ryzen 7 4700U with Radeon Graphics Memory: 15.0 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: LENOVO Product Name: 82FN System Version: Yoga 6 13ARE05 ADDITIONAL INFORMATION This is some other information that suggests that this might be a problem either related to Dolphin or QT: "Exception in get_child_count: atspi_error: The process appears to be hung.".
*** Bug 474524 has been marked as a duplicate of this bug. ***
I have reworked the accessibility code of the Dolphin 25.04 release. I have also interacted with the maintainer of Orca who implemented some performance improvements for Orca 48 I think. At least from my testing, navigating files and folders with arrow keys is now instant while using the Orca screen reader. I will therefore mark this bug report as resolved for now. If you are still experiencing this slowness with the newer software versions mentioned above, please let me know. There might be other causes then.
