Description L. C. 2023-06-15 01:14:18 UTC
SUM:
Strokes in two parts of the screen after use Image > Mirror Image Horizontally, when using the eraser.


STEPS TO REPRODUCE
1. Go Image > Mirror Image Horizontally
2. Then go back to previous, original mirroring, Image > Mirror Image Horizontally again
3. Now use the eraser in the left side of the canvas

OBSERVED RESULT
the erasing affect also the right side of the screen, too, reaching two places at the same time.

EXPECTED RESULT
the erasing should happen only where the cursor would pass over.

Hi, L.C.!

Are you sure you didn't activate the mirrored brush in the toolbar instead of image mirroring? We have three ways to "mirror the image". Could you make a video screen recording of the issue?
