GIFs are sometimes exported as solid color
Pixelorama version: 0.10-stable
OS/device including version: EndeavourOS 5.17.5, Mesa 22.0.3, Radeon RX 5700 XT MrTriPie was able to reproduce the issue on Windows 10
Issue description: When exporting images with more than 256 colors Pixelorama sometimes exports a GIF which is just a solid color. Exporting images which don't require quantization it seems to work properly. I expect the issue is somewhere in that code.
Steps to reproduce:
This standard test image of Lenna causes the issue sometimes:
I can confirm this on Linux with the master branch, but can't seem to produce it on v0.8.1 and below (this needs further confirmation)
I think this may due to multi-threaded rendering not working properly in Godot 3.x. In Godot 4 it outright crashes with the compatibility renderer, so I disabled it. I tested gif exporting with multi-threaded rendering with the Forward+ as well, and in both cases this bug doesn't seem to be longer reproducible in Pixelorama v1.0, so I'll go ahead and close the issue now.
