Issue created Jan 12, 2020 by Thomas Silton@BigDulles

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

What happened?

  • 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.

Profiling

See #1577 (comment 270259557)

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.
