Bug description

Hi,

When I first upgraded to 3.14.0 on my Win11 23H2 the UI was very slow. It was most visible when scrolling down the folder view:

Moving the scrollbar always takes 1-2 seconds (seems like freezing for a short while). I then downgraded all my clients to 3.13.4, which is working fine.

Today I decided to test with both 3.14.1 and the latest nightly build (windows-20241020.msi) and the situation is the same, hence this bug report.

I read that there have been issues with dark theme but it is the same with dark/light theme.

I experienced this on 2 clients (a HW one and a VM) connected to the same account. One is using Virtual Filesystem, the other is fully synced.

Regards!

Steps to reproduce

  1. Open settings
  2. Move to an account
  3. Scroll down the folder list

Expected behavior

scrolling should be smooth

I'm quite surprised this hasn't been reported by others.

Here is 3.13.14 working as expected when moving around the folder list:

And here is the same folder list on 3.14.2:
https://github.com/user-attachments/assets/767c2a1d-e1bb-4685-b3f2-14af4948411a

Again, going back to a light theme doesn't change this behaviour. Both have been recorded in Win11 23H2. The largest diff for me is QT5 vs. QT6.

I have also looked at the threads activity using Process Explorer:

  • On 3.13.4, moving the list mostly shows activity of the nextcloud.exe thread. The Qt5Core.dll threads remain idle most of the time.
  • On 3.14.2, moving the list shows activity on the nextcloud.exe thread as well as 8 Qt6Core.dll threads.

Someone told me this would be solved by restarting explorer.exe, unfortunately for me this is not the solution.

Rebooting or restarting explorer.exe do not solve this problem.

The Windows 11 desktop is also otherwise idle.

I have the feeling that the folder list takes an unusual amount of time to be created. This might depend on the number of top-level folders, which is 57 in my case. Maybe a shorter list would be faster, but this is still a major regression when compared to 3.13.x.

Cheers!

I can confirm this issue. I've experienced significantly poor performance with version 3.14.x. Reverting to 3.13.4 has resolved the problem and is working smoothly for me.

I am using Windows 11 23H2.

Sorry for posting wrong conclusion before, because at that time through other wrong comments and tried to restart explorer.exe method briefly restored a short period of normal side of the comments, later on the windows 10 status bar extreme lag and upload bandwidth is only 90k or so, and page animation effect is delayed seriously, retried the above method has no effect so deleted the comments. The system version I am using now is windows 22H2 ,back to use nextcloud desktop 3.13.4 without the above problem.
