gif demonstrating the issue
Issue:
A layer setup using "blur filter masks" slows down Krita severly.
It is not excactly a bug, but a heavy limitation in image editing,
Test file:
1200 x 900 pix, 16bit integer (attached to this report).
Test system:
CPU: Intel Core i7 - 10750H (6 cores, 12 threads)
Max Turbo Frequency: 5.00 GHz
Processor Base Frequency: 2.60 GHz
Ram: 16 GB
Storage: NVMe SSD
GPU: Nvidia RTX 2070 MaxQ + Intel® UHD Graphics
Steps to reproduce:
- please watch the provided gif
The gif animation shows the time it takes to enable the layer groups containing
the blur filters. But changing something in the layer stack also is slow. If
the blur filters are disabled everything goes faster.
Tested on Krita 5.2.13 and Krita 5.3
