Description Paul Geraskin 2014-03-14 10:14:36 UTC
Hi devs.

Filter Brush does not work with UnsharpenMask and GaussianBlur.

I select standart preset "FX_blur_light". Choose UnsharpenMask or GaussianBlur. And filter brush does not work.

Thanks.
Comment 1 Halla Rempt 2014-03-14 10:44:25 UTC
Hm, if I just create a preset from scratch for gauss blur or unsharp mask, the filter brush just works. Could it just be an incompatibility in the settings?
Comment 2 Paul Geraskin 2014-03-14 10:58:44 UTC
Dmitry confirmed that he has the same issue on his machine.
Comment 3 Halla Rempt 2014-03-14 11:02:40 UTC
And if you _don't_ use that preset? But go to the brush editor, select filterop, select gauss blur or unsharp mask and make sure the settings do something? The default settings for unsharp mask all seem to be zero.
Comment 4 Halla Rempt 2014-03-14 11:04:40 UTC
Out of the box, the fx_blur_light preset uses blur. If I select gauss blur when that preset is active, the radius is 0.5. I guess that that doesn't do much. Same for unsharp mask, where it's all 0.
Comment 5 Paul Geraskin 2014-03-14 11:13:00 UTC
Ok i did it:

- Pressed "Default Preset"
- Selected Filter Brush
- Choosen Unsharpen Mask filter

Brush works like Blur filter. It blurs. But it should sharpen.

Possibly, new filter is not switched when we make a new choose.
Comment 6 Halla Rempt 2014-03-14 11:24:54 UTC
Yes, _that_ I can confirm. Fixed the subject.
Comment 7 Halla Rempt 2014-03-14 11:30:21 UTC
It isn't that the filter isn't switched, though -- check with some other filters.
Comment 8 Paul Geraskin 2014-03-14 11:43:13 UTC
Pixelize, Invert and others filters works ok.
Noize filter - crash.

I think GaussianBlur and UnsharpenMask should be checked.
Comment 9 MichalG 2014-03-25 01:01:02 UTC
I noticed this irritating bug with bad acting of brushes that use sharpen or blur as well.
Could it be fixed soon and in what release?
Comment 10 MichalG 2014-04-05 19:27:22 UTC
There was Krita v2.8.1 released recently, but the (above described) bug remains... :(
Comment 11 Halla Rempt 2014-04-07 08:10:50 UTC
Yes... There'll always be bugs that won't be fixed in time for the next version...
Comment 12 MichalG 2014-04-19 12:15:39 UTC
OK, I can understand, but could you let me know when this bug will be
corrected, anyway?

Comment 13 Dmitry Kazakov 2014-05-05 08:37:21 UTC
It might be some transaction-related problem, which prevents Unsharp Mask accessing oldRawData

Fix using a transaction in the Filter Op

Otherwise the filters like Gaussian Blur and Unsharp Mask will not work
correctly.

Well, I didn't find it fixed in latest bugfix version (v2.8.3) but I
hope I will see it in 2.8.5 or 2.9!  :P
