SUMMARY
Creating new brush profile from already existing one with low-resolution canvas makes its icon blurry (less pixels than original image had)

STEPS TO REPRODUCE
1. Make a canvas with low-resolution (i had 120x80)
2. Open any brush by "Change brush's parameters" (or something) button
3. (Optional) Change the brush
4. Click "Save new brush profile". While saving there is an image of brush and it is low-resolution

OBSERVED RESULT
After saving, there is a brush in "Brush profiles" category. Its image is blurry because of scaling low-resolution icon of this brush

EXPECTED RESULT
A normal brush with normal icon as its "parent" brush had
