If you enable colour management, drawing becomes impossible, gimp slows down so much that the brush moves jaggedly. With colour management disabled it works fine.

On a positive note, I just compiled wavelet decompose plugin and it works just fine. I'll see if GMIC works soon.


...whoops, I forgot I already had gmic in my home plugin directory. Yeah it works.

Aha.

I do not have such problems. Maybe:

I have an Intel i7-870, maybe it is fast enough so gimp doesn't slow down. (what kind of Processor do you have?)
You have a picture, that is complex and I took just a cheap picture to test it. (can I have one?)
I have done some changes in gimp, so it is linked againt liblcms2-2, that is maybe faster (I send the changed data)

OnkelHatti,
My box has an AMD Phenom II X4 925 processor and 8GB RAM.
I have the same problem.
I tried Gimp-2.9.1,same problem!

Edit:If it was an lcms problem then why doesn't gimp-2.6 suffer from it?
Also have a look at this bug:
https://bugzilla.gnome.org/show_bug.cgi?id=645345
Especially Mitch's reply at the end.

if it wasn't already mentioned in this thread, gimp.org is now officially announcing it too, so it's really "officially out" now.

I have a build environment here, but I'm in no rush after 3.5 years. I'll wait before the 2.8 package hits Debian SID.

I'm not looking forward to having to re-do my Beginning GIMP tutorial ... gah.

I hear you Griatch.
Fun times ahead!

GIMP gimp-2.8.0-setup.exe released!!!
http://sourceforge.net/projects/gimp-wi ... P%202.8.0/

Thanks for the heads up pogogogo. I indeed uninstalled RC1 and installed 2.8 full. Of course 2.6.12 got uninstalled again (but I will fix that later). They fixed the tif but, but still MM's Labcurves program won't work (but sigmoidal contrast does). The jpeg preview save size bug still exists though (not sure why this didn't get addressed). Also, gimprc error (which prevents the path for both pspi and user filter to exist concurently) also exists, but I have to have PSPI so I'll live with the Filter Factory convertor fiasco (each time I run the user filter, I have to point to the guf files) for now. Looks like that won't get fixed; sad for me. Not sure if there is a brush sluggish issue yet since I haven't tested that but I believe others have said it's still there. Anyway, I'm going to parallel post this respont at gimpusers too since maybe the developers read stuff there more then here. All in all, only the tif bug appears to have gotten fixed between rc1 and now.

Lylejk i didn't try because from long i don't use PSPI but i believe this workaround may fix :

1)load gimp,
2) use the userfilter setting the correct path
3) without closing gimp, start explorer as admin, search the gimprc file, enter propriety
...and check the "read only" box

obviously in case you will want change again something in the gimp preferences you will need first to make again the file writable, but for that you just need to unmark the same box

if your diagnosis is correct what i suggest should fix

Never thought to make the gimprc read only. Will give that a shot PC and will either edit this post for follow up with yea or nea.

edit:

Did not work PC; at least the entry didn't get removed. lol

Will now go back to the way it was (and do the fixes so Impressionist will work again; Paint Engine too).

Sorry that doesn't work
I am not going to install 2.8 now i am waiting for a partha (or samj) portable, better if at 64 bit

But at soon i got i will look also to that and see if i may found some solution (if the new build didn't already solve )
