Performance issue: >160 squares usability limit

[curliq]

I came across the project after looking for affinity designer alternatives for linux, and quickly ran into major performance issue, Not sure if it's a bug or just browser limitation. I will share as much info as I can

I'm trying to create a 20x20 grid:

1. Create a 50x50 pixel square, fill color grey
2. Create a 50x50 pixel square, fill color black
3. Copy and paste until 20x20 grid reached

But after adding the 2nd row, it became laggy, and after adding the 8th row it became unusable, where pasting a new row freezes the window for over 10 seconds.

This is what I'm trying to do for reference:

Info:

• I've tried doing the same with Affinity on Wine, and it works smoothly.
• Using Zen (firefox)
• Tried with chromium too (slightly smoother, but same result after row 8)
• OS: Fedora 44, Wayland, Niri
• Hardware: Thinkpad p14s gen 5, amd ryzen 5 pro 8640HS, amd radeon 760m graphics, 64gb ddr5

I have the same issue with the flatpak app (1.0.0-rc6)

For now you can try to use the repeat style nodes to create grids which should hopefully perform quite a bit better:

instead of the assign color node, you could also use a read index node, feed it into a modulo and then a switch node to assign a color.
