Further note: there are 2 other SVGs in the test case package. It seems to be necessary to have those in the mix to trigger the crash issue. Try removing any 1 of them, and the test case will start working.

For the most part, the test case code has been whittled down to the bare essentials.

This issue seems to be related to rasterization in chromium and not to the Mac Book actually. I assume that just MacBooks with a dedicated graphics card have rasterization turned on by default.

If I use `about:flags` to turn on "GPU rasterization" and try to load the above example, the tab never renders, but will be stuck with 100% CPU load forever (according to Chromium task manager).

I am running Chromium 63.0.3239.132 on Archlinux and attached the output of `about:gpu` and `about:vesion` after turning on the "GPU rasterization" flag.

I can reproduce this error every time trying to load the HTML. I can also verify, that it doesn't matter whether you open the file via HTTP or file protocol.

I of course always meant "GPU rasterization" when talking about rasterization in the above comment.

And apparently my `about:gpu` wasn't attached correctly, so here again.

Unable to reproduce the issue on reported chrome version 63.0.3239.132 and on the latest canary 65.0.3322.0 using Mac 10.13.1 with the below mentioned steps.
1. Launched Chrome 
2. Downloaded and extracted the test file "simpletestcase.zip "
3. Navigated to http://www.svgminify.com/
4. Loaded Kibana.html and in other tab loaded kibana.svg
After hitting start button in one tab we see an error and in the other some script is shown, in the process we didn't see any crash/hang. Attaching the screen cast for reference.

@Reporter: Could you please have a look at the screen cast and let us know if we have missed any steps while reproducing the issue. Any further inputs from your end may help us.

Thanks!

The screencast seems to be broken for me.

Thus I will rephrase the reproduction steps:

1. Go to `about:flags`
2. Enable "GPU Rasterization"
3. Restart Chrome
4. Download and extract "simpletestcase.zip" somewhere
5. Open the "Kibana.html" in the browser.
6. Wait a bit and the tab should freeze very soon (i.e. the GIF is not playing anymore), also you can check the chrome task manager, for me the tab was stuck with 100% CPU load

I am also not able to view the screencast.

Comment #7 has the right steps.

From my report:

> 2. The page tab hangs and eventually crashes, which is evident by the animated gif not working
> 3. Run `Kibana_files/kibana.svg` through http://www.svgminify.com/

Step 2 is sufficient for seeing the tab hang - the page will not finish rendering correctly and as said in Comment #7, CPU load goes all the way up.

Step 3 is for "fixing" one of the SVGs on the page to make it somehow usable by Chrome to render in the test case without getting stuck.

Thank you for providing more feedback. Adding requester "vamshi.kommuri@techmahindra.com" to the cc list and removing "Needs-Feedback" label.

This issue seems to require a dedicated GPU for MacBook hardware (so you most likely need a 15" MBP).

It also reproduces on my Windows desktop, which has a dedicated NVidia GeForce GTX 960. I can make the page load by disabling hardware acceleration via the Chrome flags menu, but all browsing becomes noticeably slower.

Chrome version: Chrome/63.0.3239.132

Crash report for #0: crash/b85cd7037245be02

It looks like the SVG takes a very long time to render and it causes the renderer process to hang and be killed. Not sure why it takes so much longer to render on some devices than others.

The stack of thread #11 in the crash report makes it look tessellation-related. +senorblanco

GrTessellator: hang fix.

Some edges are not coincident with their own endpoints (because floating
point). If this happens for an edge which is a right-enclosing-edge
during the Bentley-Ottman simplify() pass, we end up an infinite loop
attempting to split the edge, since the edge is never to the right of its
endpoint.

The easiest fix is to simply remove the right-enclosing-edge splitting
code. This code was originally added before we had proper
active-edge-list rewinding, and should no longer be necessary.

Revert "GrTessellator: hang fix."

This reverts commit 050c86768a2c24c62655f53ef9b685d40477eccb.

Reason for revert: layout test diff in Chrome roll?
