CSS custom cursor origin does not change at the exact same time as the cursor. |
|||||||||||||||||||||||
Issue descriptionChrome 54.0.2837.0 OSX 10.11.6 What steps will reproduce the problem? (1) Visit https://garron.net/test/pink-cursor/ (2) Hover over a link. What is the expected output? The cursor changes from pointing to the upper-right to pointing at the lower-left instantly (pointing at the same point). What do you see instead? The cursor image often changes to the lower-left-pointing icon a split-second *before* or *after* its origin changes. The opposite happens when moving out from the link. It doesn't seem to be possible to screencapture this, but I can clearly see it on the screen. I aimed a phone at the monitor and attached the resulting evidence to prove I'm not crazy.

sashab@: Based on a cursory glance at Issue 610635 , seems you're possibly involved with custom cursors. Could you possibly triage or pass this on to someone who knows where to put it?

I couldn't repro any weirdness on Windows, but on Mac I do get an odd behavior which is subtly different than your movie. In my case, I see the custom cursors swapping out for the system cursor at multiple different sizes. Perhaps related to the fact that the custom cursor is a 46x46 image instead of a more standard cursor size?

I'm struggling to repro, but it's likely that I'm just not seeing the split-second difference, even if it's there. (I needed to step through the movie in the original report practically frame-by-frame to see the issue.)

Thinking this is a Mac problem, since its only appearing on Mac? Not sure who to route this to... Tim any ideas? Maybe tapted@

There's probably a lot of latency feeding up the cursor information from the renderer process to the operating system. But this doesn't feel unnatural to me. I don't think it's worth optimizing for.

I tested this on linux and mac and I couldn't repro it any more. I'm going to mark as closed. lgarron@, could you please re-open if I'm missing something?

Reproduces for me, linux M63.

Reproduces for me in Figma (MacOS, both in browser and Electron wrapper app) and Framer shared prototypes using the loupe pointer, among others. We've done some digging: the effect is larger the bigger the delta between mouse pointer hotspot locations, and more pronounced when retina pointers are being used. It also occurs when swapping between system pointers and custom pointers. |
