Inkscape 1.0 lags considerably on Mac Catalina
Steps to reproduce:
- open Inkscape
- import image or draw a simple rectangle
- zoom in
- try to scroll or pan
- Slow to update, particularly on scroll
- Substantial pause before rest of screen loads.
- Performance is worse as you scroll (25% zoom is still responsive, 200% has 1-2 second delay before screen loads)
And things that are normal:
- Menus are still normal, so issue with the canvas rendering
- In latest builds, hiding toolbars/rulers/status bars doesn't help
- Doesn't affect a blank document
Informally this is as bad as a 2-3 fps frame rate.
What should have happened?
- I never had this issue with the old 32 bit + xQuartz system, it was smooth and didnt slow down at all. Not sure if this is a Mac or an Inkscape issue.
Workarounds (varied success):
- Open in Low Resolution makes it usable (see #2214 (comment 326655488))
- Inkscape might have to disable High resolution from Info.plist per #1577 (comment 330987062)
- In monitor settings, set color profile "sRGB" instead of the default (see #1577 (comment 334401685))
- Disabling statusbars/rulers (see #1577 (comment 270254900) , not working in later versions apparently)

In the old 32 bit + xQuartz system, scrolling was smooth. On Ubuntu, this is not present in 1.0.
