Bug ID: 427833
Summary: Artifacts with isometric grid because of the outline
Product: krita
Version: 4.4.0
Platform: Mint (Ubuntu based)
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: OpenGL Canvas

Video showing artifacts
SUMMARY
I get weird artifacts when trying to paint on 100x100 pixels canvas with OpenGL
turned on and an isometric grid (standard settings). The artifacts happen
inside the outline and where the outline already was. After a moment, a proper
grid reappears. The artifacts look like skewed fragments of the grid (they have
different angle than the actual grid).
STEPS TO REPRODUCE
1. Create 100x100 pixels canvas.
2. Turn on "Show Grid", switch to "Isometric" in Grids & Guides docker.
3. Try to paint or just move the cursor around on the canvas.
OBSERVED RESULT
Artifacts show up.
EXPECTED RESULT
No artifacts.
