Intermittent hangs/freezes for a few seconds when browsing (identify what is cause of freezing)

Question

Is there an easy way to identify what is causing DOPUS to freeze intermittently for a few seconds?
(Does not seem to freeze with fresh install, but after applying backup, the freeze issue appears).

Alternatively:
Is there an easy way to identify exactly what changes are applied when restoring a backup?

Issue description

While browsing folders, or switching tabs DOPUS will sometimes freeze for a few seconds (as if it was waiting for an HDD to spin up).
Initially I thought this was actually caused by HDD/Windows misbehaving.
However on a different computer with only SSD this issue is still persistent (at least after my DOPUS backup has been restored).

Note:
I tested for a short while on a fresh install, and it did not seem be freezing then.
So it seems that something that the backup is applying is causing the issue.

If it seems to be config related, try these one by one:

  • Disable all scripts
  • Turn off all columns other than Name
  • Turn off each of your toolbars
  • Reset the Status Bar definition to default, if it's customized

The issue will most likely be inside one of those things, if the config is causing it and it doesn't happen on a clean install.

If you work out which and still aren't sure what might be causing the problem, let us know what you find and we can make more suggestions.

Thank you for the quick response.

I have performed the following actions:

  • Unticked all scripts unde "Prefrences -> Toolbars -> Scripts"
  • Edited "User Default" under Prefrences -> Folder -> Folder Formats -> Default Formats
    Only left the "Name" column
  • Clicked "Revert to Default Toolbar Set" / "Factory Reset Toolbars"
  • Deleted all "Status bar definition" text under "Prefrences -> Display -> Status Bar"

Unfortunately problem still persists.

However after recently closing the folder-tree, there hasn't been any freezes for a few minutes now.
After reopening the folder tree (it took a few seconds to open), then I managed to provoke a freeze within 30 seconds.

Will restore the backup again and then try to use it without the folder-tree for a while, to see if it is the cause of the issue.

Out of interest, do you have Dropbox installed?

Not dropbox, but I do have Tresorit and pCloud.
However the issue is also present when i open up a Sandbox and just install dopus and apply the backup.

I will experiment a bit more with it tomorrow.

Turns out that what i do have, is a folder in Favorites that link to a non-existent network location. :roll_eyes:
Removing this folder from favorites (favorites are also displayed in my folder-tree) seems to remove the issue.

So it seems like it is trying to refresh or load this network folder, even if I browse entirely different locations on my local drive.

I tried installing an old version 12.4 I had lying around in a Sandbox and then applied the backup (including the link to non-existent network folder), and it seems like the issue is not present here.

I suspect that this issue could also cause some micro-stutters even if the network location was available, so possibly a bug?
Do you know if anything could be triggering a refresh of the Favorites items (in either the UI thread, or in such a way that it blocks the UI thread)?

I have only run these tests for a short amount of time, so it may have been coincidence.
I will observe how the system behaves over time.

Update:
There has been no freezes after removing the network folder from the favorites.
So it is almost certain that it was the cause of my issues.
