Restoring the image to normal rendering state, tile by tile, by drawing on it

SUMMARY

When increasing the canvas size, some new area is incorrectly shown as transparent until interacting with it. Please see the screenshot for the idea of how it gradually, tile by tile, refreshes to the normal state.

STEPS TO REPRODUCE
1. Create a new image
2. Activate the Freehand Brush tool
3. Choose some non-while color as a foreground color
4. Go to Image → Resize in the top menu, increase width by 200 pixels and press OK
5. Observe that some or all area of the image is shown as transparent, or try to scroll the image with the middle mouse button – and after that the image may be shown as transparent
6. Then after drawing on it, for example, it’s made visible again in some chunks affected by drawing (such as on the attached screenshot)

OBSERVED RESULT

The image is fully or partially rendered as the checkers pattern (for transparency), which is incorrect.

EXPECTED RESULT

Image shouldn’t require any actions from the user to be rendered properly.
