Description Raghavendra kamath 2016-04-08 18:03:53 UTC

In Krita latest git , if you go to apply a filter to an area which is under selection , the on canvas preview of the filter turns white instead of showing the actual preview.

Reproducible: Always

Steps to Reproduce:
1.Open krita and create  a new document
2. draw something or fill it with some color
3. Select a region with rectangular or any other selection tool
4. trigger any filter for example press Ctrl + U for Hue saturation filter
5. Check the preview checkbox in the dialog if it is not checked by default

Actual Results:  
the preview is white

Expected Results:  
The preview of the filter should be shown normally

I can confirm for several filters like hsv, levels, color balance, blur and such.

It does not affect all filters, though. Sobel, mean removal, wave and more have working previews.

Hm, I don;t get a white area, which might be because I haven't got opengl in this vm, but it also looks like some filters have stopped doing anything!

Comment 3 Marcus Kjeldsen 2016-04-12 08:50:51 UTC

Ah, yes if I disable opengl I don't get the white preview, and it seems that the filters aren't applying anything.
