Graph lines not appearing on Weather Underground
Perhaps someone can help me track down the cause of a strange problem. I run SeaMonkey on various computers, and usually check the weather on Weather Underground. Until recently this has worked fine. The forecast looks like this:
However, as of a few weeks ago, one of my computers no longer shows the red temperature line in the forecast graph:
All computers are running the same version and build of SeaMonkey:
User agent: Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0 SeaMonkey/2.46
Build identifier: 20161222000000
The computer that doesn't display the red line is running openSUSE Tumbleweed, while all the other computers are running openSUSE Leap 42.2. The disappearing line problem occurs even when viewing the page in a fresh profile in safe mode, so it's got nothing to do with any add-ons or site-specific settings saved via cookies.
Any idea what the problem might be?

Yes, it's checked (by default, in fact, as the second screenshot, which is from a fresh profile, demonstrates).

On the one computer, do other browsers show the red lines?
On my end it work with (by allowing):

Yes, the red line displays fine in Firefox, Chromium, and Konqueror.therube wrote:On the one computer, do other browsers show the red lines?
As far as I know, nothing in my SeaMonkey browser is "disallowed". The problem occurs even when running in safe mode with a new profile, so the browser shouldn't be blocking any sites by default.On my end it work with (by allowing):

Re: Graph lines not appearing on Weather Underground
I've noticed the problem is happening with other websites as well. Google Maps, for example, does not highlight the route when asked to give driving directions. You can see this in the screenshot below, where the same route is shown in Firefox (left) and SeaMonkey (right):

It also displays fine on my SeaMonkey in Linux.Psychonaut wrote:Yes, the red line displays fine in Firefox, Chromium, and Konqueror.therube wrote:On the one computer, do other browsers show the red lines?
As you've already tried a new profile then I've no idea what to suggest. However, whatever it is, it is a Canvas element related problem, as both WU and Google Maps are using that in those examples above.

Re: Graph lines not appearing on Weather Underground
Yeah, I was thinking the same thing. I suspect it is a problem with how my browser is rendering WebGL. When I visit some WebGL tester sites (but not all of them), I get a blank canvas.
I tried using the official nightly build, as well as the unofficial "contributed" 64-bit build of 2.46, and the canvases display fine for me with these versions. So I'm guessing that there is something wrong with my OS's packaging of SeaMonkey. I have reported it as an openSUSE Tumbleweed bug: Bug 1045848

Re: Graph lines not appearing on Weather Underground
In case anyone else here was experiencing this problem, I just wanted to report that the cause seems to have lain in the GCC optimization flags used to build SeaMonkey. While these flags worked fine when compiling SeaMonkey with GCC 6, using the same flags to compile SeaMonkey (and Thunderbird) with GCC 7 resulted in WebGL display problems. Disabling the optimization flags when building with GCC 7 worked around the problem (though they may have resulted in somewhat less efficient code). Further details can be found in openSUSE bugs 1045848 and 1042090.
I'm not sure whether this was a problem with GCC or with SeaMonkey; regardless, the problem seems to have been fixed as of a few months ago. At least for me, the current openSUSE RPMs (both the binary ones from the official repositories and the ones I build myself from source) work fine.

Re: Graph lines not appearing on Weather Underground
(Pale Moon, with its recent v28 release, also ran into optimization flag related issues [& other issues too] . They have since de-optimized.)

Re: Graph lines not appearing on Weather Underground
I am compiling 2.49.x with gcc 5 only. Now 5.31. Anything higher produced visible redrawing artifacts. Tobin said Palemoon was fine with 7 but it looks that this might not be the case after all. Bill (wg9s) does clang builds under Linux. They seem to be fine even with bleeding edge compiler.
