Very large patterns on phones can cause the browser to run out of memory. At which point the browser will refresh/restart.

Re: lifeviewer bug
I'm not sure if this thread is for any bug or a specific one, but LifeViewer just isn't working for me at all anymore. When I click on View, it flashes and does not show any pattern. Does this happen to anyone else? I'm using Chrome Version 94.0.4606.71 on MacOS 11.4.
Re: lifeviewer bug
Please post a link to the page that is not working. Also please open the Chrome developer console and let me know if there are any error messages when you click.pcallahan wrote: ↑October 8th, 2021, 2:00 amI'm not sure if this thread is for any bug or a specific one, but LifeViewer just isn't working for me at all anymore.

Re: lifeviewer bug
It's every page when I try to run LifeViewer (or it starts automatically). Chrome developer tools doesn't show any obvious problem. The API calls all return 200, and there is nothing on the console. It flashes when I move my mouse over it and otherwise leaves the cell area unrendered. Here's a screenshot: This is on my work computer and maybe that is configured in some way that interacts badly. I can try another computer at home.
Re: lifeviewer bug
Very strange indeed. Would be very interested in results from trying on your computer at home. Also do you know if it works in other browsers like Safari?
From the screenshot it looks like the image data buffer used to render the cells contains zeroes (which would make the pixels transparent with an alpha of zero). I can't imagine why that might be happening.

Re: lifeviewer bug
It works fine in Safari. I just checked, but it's not my preferred browser. I also thought Chrome might have trouble with memory with too many tabs open, but I have closed a lot of them and restarted. That still could be the issue. I also cleared the cache. No luck there either. I guess I can use Safari as a stop-gap if this problem is limited to me.rowett wrote: ↑October 8th, 2021, 11:53 amVery strange indeed.

Re: lifeviewer bug
FWIW, I see exactly the same problem. Same version of Chrome, but on macOS 10.15.7.
Re: lifeviewer bug
I use two old iMacs.
The first runs OS X 10.10.5 and has Chrome 87.0.4280.141 installed.
The second runs OS X 10.11.8 and has Chrome 94.0.4606.81 installed.
I use the Firefox browser on both systems and have had no problems accessing www.conwaylife.com on either computer.
After reading the posts above I tried using Chrome and got the following error message on both computers.
After clicking Advanced and then clicking Proceed ... everything seemed to work correctly on both computers. But why did this happen?

Re: lifeviewer bug
I also have the same problem. I'm on Mac OS 11.5.2, and it does the flashing on only google chrome. On safari, it works perfectly fine, but on chrome, it doesn't.
Re: lifeviewer bug
The fact that the issue is specific to Chrome on MacOS suggests a chrome bug on that platform.
From some googling it might be worth trying the following:
In Chrome settings go to Advanced->System and toggle the "Use hardware acceleration when available" and then restart Chrome.

Re: lifeviewer bug
Turning off hardware acceleration does seem to have fixed it. I'll see if this affects performance for other things (I'd prefer hardware acceleration if possible.)
Re: lifeviewer bug
It seems to be fixed, although i haven't done anything with chrome since the last time i posted in this thread.

Re: lifeviewer bug
Same here, but it was an update to Safari 15 that caused it, not an update to the OS version. Having the LifeViewer window open is enough to trigger it (although it's random); no closing required.LaundryPizza03 wrote: ↑November 10th, 2021, 11:14 amIn macOS Big Sur 11.6, forum pages sometimes crash and reload when closing LifeViewer; the main page also tends to crash repeatedly.

It applies to LifeViewer anywhere, including on the wiki.

Re: lifeviewer bug
In which case it's almost certainly an issue with Safari 15. Google shows there are a number of issues with Safari 15 so hopefully it'll improve as Apple fix it: https://www.macworld.co.uk/news/issues- ... 5-3808936/hotdogPi wrote: ↑November 10th, 2021, 5:24 pmSame here, but it was an update to Safari 15 that caused it, not an update to the OS version.

Re: lifeviewer bug
Here's a few more that only appear on a Chromebook:
I have to press down Ctrl-Space for a long time before it starts stepping the selection forwards, after which it just steps it way too fast to "aim" for a specific generation.
LifeViewer completely ignores Alt-Up and Alt-Down.

Re: lifeviewer bug
I guess you just need to wait longer for the initial step. If you're holding down Ctrl-Space while waiting the keyboard repeat will create a backlog of keypresses that will get serviced once the initial step is finished.
When nudging a selection? Do Alt-Left and Alt-Right work? Do the UI buttons for nudge up and down work?
Which version of Chrome is running?

Re: lifeviewer bug
Is this because when you press Space it's stepping multiple times?
LifeViewer https://lazyslug.com/lifeviewer
Re: lifeviewer bug
OK so I need to understand the timing. For example:
- Stop any playback
- Make a selection
- Press and release Ctrl-Space
- Pattern in selection should evolve 1 generation (how long does this take?)
- Press and release Ctrl-Space
- Pattern in selection should evolve 1 generation (how long does this take?)
- Press and hold down Ctrl-Space
- Pattern in selection should continue evolving (how fast is it evolving?)
- Release Ctrl-Space
- Evolution should stop (how quickly does it stop?)
LifeViewer https://lazyslug.com/lifeviewer
Re: lifeviewer bug
Sure.
1. Stop any playback
2. Make a selection
3. Press and release Ctrl-Space
4. Nothing happens
5. Press and release Ctrl-Space
6. Nothing happens
7. Press and hold down Ctrl-Space
8. Around half a second later, the pattern in selection starts evolving, and does so at a rate too fast for me to aim for any specific generation
9. Release Ctrl-Space
10. Evolution stops immediately
