Safari Desktop rendering error

[blurfl]

On the Desktop version of WebControl the Safari browser (Version 12.0.2 (14606.3.4)) mis-renders the workarea when zooming or moving the window. Clicking on the window or changing focus to a different program causes the workarea to render to correctly. Safari mobile does not have the issue.

Hmmm.. I used svg.js to handle all the graphics. @johnboiles, do you see this when you run safari desktop (I don't have a mac)

I can try tonight. @blurfl can you post the gcode?

The gcode in the image was one of the files in the WebControl standard list, but the issue isn't related to the gcode. I think this one is WebControl.nc. I'd say it's a Safari rendering thing because on the same machine Firefox works correctly.

Does it look different each time you zoom, or does it just seem like part of the svg doesn’t redraw.

I checked the svg.js github repo as well as the panzoom plugin github repo for issues as described and I don't see anything regarding desktop safari rendering issues. It does seem like a safari thing. After doing some reading, it looks like most browser's svg implementation are rather lacking. I've contemplated switching to a new renderer. I'd like to be able to render the gcode in 3D so you can see passes at different depths and verify tabs, etc.

I would say that part of the window doesn't redraw correctly and the error is symmetrical around the 0,0 point of the workarea. The workarea grid is affected as well, and occasionally the error 'corrects itself'.
