How it looks / How it should look
SUMMARY
Sometimes I use Krita as image editor to avoid using GIMP, while the general
experience is pretty good, but I found a very annoying bug when transforming
the layers, where the layers bellow the transformed image get blurred after
transforming it. But it only occurs when the "accurate instant preview" is
enabled.
STEPS TO REPRODUCE
1. Pick two images and insert them in your file (drag and dropping or pasting),
at different layers
2. Select the first layer in your list and transform it with CTRL+T
3. When transforming, move it to above the second layer, zoom out quickly with
the mouse scroll and press enter
OBSERVED RESULT
The layer bellow get blurred after transform.
EXPECTED RESULT
The layers bellow don't get blurred after transform.

ADDITIONAL INFORMATION
- I'm using the flatpak version with an AMD Polaris card, also tested the
appimage and happened the same bug
- Two possible temporary workarrounds are: Change the Settings>Configure
Krita>Display>Canvas Acelleration>Scaling Mode to "Bilinear Filtering" instead
of "Trilinear" or "High Quality Filtering"; When using the transform tool,
change the preview mode to "Fast" or "Accurate" instead of using "Accurate with
Instant Preview".
- If you transform the blurred layer, it goes back to normal.
- I don't have access to other graphical API that aren't OpenGL.
