Operating system: Windows 10 64bit

Broken: 2.80, 2.81
Short description of error
I'am using UV maps of very high resolutions - 12000x12000 px. It is key point in projects I develop. In B2.79 it was not a problem. In 2.80 and 2.81 during export UV layout to png RAM consumption going higher, and higher until "eat" whole RAM - then Blender crash or in rare occasion report problem: Memory Error.
In 2.79 all works ok. I have 32 GB RAM in computer I normally work, but even on machine with 8GB I was able to get 12K UV Map with no issues. In 2.79 used RAM is much smaller and never reach even half of available RAM.
First I thought, that it depend on how dense and complexed is UV but it also happen with simple cube.
Exact steps for others to reproduce the error
- Open Blender
- Go to UV Editing
- Select default cube
- Enter edit mode
- Unwrap cube
- Export UV Layout in 12000x12000 px
- Wait for crash.
