Darktable 5.6.0 Slow

I am using Darktable 5.6.0 on windows 11 and up until today, I have had no issues.
When I first installed the version above, when it loads form the start, there are many other “windows?” that are also opening in the background which I never had happen before.
Now today I seem to have 3 new issues that I never had before.

  1. Very slow when switching between light table and darkroom
  2. Very slow after taking snapshots and want to view them to see the differences in an edited photo
  3. Sometimes, I even get a message that says “Darktable is not Responding” when I use snapshot and I have to shut the program down and restart but will also get the same message again.

Other programs on my computer appear to be working fine.

Can someone please help?

Thank you

I have the same problem.
When 5.6.0 starts (windows 11) it flickers through a lot of screens. This is an issue for 5.6.0 only. It is especially a problem the first time darktable starts after you have powered on your computer. Annoying!

See attached video.

I have not experienced other problems but darktable 5.6.0 seems slower than older versions.

You are probably experiencing a known bug, probably fixed in 5.6.1.

Will the issue having to do with slow response and “darktable not responding” also be addressed in 5.6.1?
Thank you

Possibly this known issue:

The video Olaf has supplied looks very much what is happening to mine as well when it first loads.
The “Darktable not responding” message very slow to load and view snapshots is an issue however. Sometimes when i switch from one edited image to another in snapshot, i see half of the old image while the new is loading. Again i think because its moving way to slow. Never had this issue before. I downloaded 5.6.0 from darktable site.

Can i unstall the 5.6.0 and reinstall the previous version for now?

Should be fine as long as you didn’t use any 5.6-specific features like Color Harmonizer in your edits. I’d personally recommend installing the current nightly.

No matter whether you decide to down- or upgrade: Just give it a try: Backup your config-dir beforehand and off you go.

I have an older back up saved. If I back up the 5.6.0, wouldnt i have the same issue when i go to use the backup? I assume best to uninstall through Control Panel and not just installing a previous version and having it uninstall?

Thank you

I am not sure I understand what you mean. I think you should backup the config-dir not the 5.6-program-files.

“older backup” = no backup :wink: .

I’d recommend the following: backup the config-dir, uninstall 5.6, install 5.4.1 and see how that goes. If you have issues with 5.4.1 you could try uninstalling that and going with the nightly. Maybe uninstalling previous versions is not necessary - I am not totally up to speed with the windows-installing routines.

Or just wait some more. I think 5.6.1 is not far out.

Best then I’ll wait. Hopefully all will be good with 5.6.1

Thank you

Well i just installed 5.6.1.

It is back to being faster again, no lags.

There is still one issue however. Right after darktable opens, i am still getting about 5 -6 different screens poping up when darktable immediately opens up. There are fast enough that i cannot read what they are.

Any suggestions?

Thank you

You’ll probably have to wait for 5.8 in December for the lightshow to stop.

Yes, Im using windows 11. Thats fine if I need to wait for 5.8.

The “pop ups” aren’t slowing anything down are they? Just annoying.

Other than that, all good !

Thank you

I can’t directly compare but I don’t think they are slowing anything down; possibly the startup.

I believe you are correct. It just seems that I have to wait just a little longer load. Thats not a big deal. The program running slower was, but seems to be much better with 5.6.1. Looking forward 5.8

Do you have any idea as to why all the “pop ups”? If you need a video, i can take so you can see what’s happening.

Thank you for your help

Yes, see this issue: Prevent terminal windows from popping up during start on Windows · Issue #17193 · darktable-org/darktable · GitHub

To hide that pop ups you can start DT from command prompt, or create a desktop shortcut using the following as target:

C:\Windows\System32\cmd.exe /S /C "start /B "darktable CMD" "C:\Program Files\darktable\bin\darktable.exe"  > "%USERPROFILE%\Documents\Darktable\log.txt" 2>&1"

Well, Im not a computer savy guy. So im not going to try setting up Commands to start darktable.

Its just an annoyance at this point and as long it can be fixed in 5.8 it will be a Christmas present.

No need to answer right away, but why would this have just started? All of the previous versions started just fine.

Than you again.

You can try this shortcut. It is just a windows desktop shortcut with @leonidas111 fix. After extracting it should work plug and play as long as you installed darktable with its default settings.

Side-Effect: One terminal window staying open in the taskbar next to darktable.
