threejs.org/editor causes Pale Moon to crash

Unread post by alerikaisattera » 2020-11-27, 06:35

Running Pale Moon 28.15.0 on Manjaro

Visiting threejs.org/editor results in crash with SIGSEGV. That website works with no problem in any other browser.

According to my friend whom I asked to test this, this occurs on Windows as well.

Confirmed. Seems to be the same reason as Issue #1624 (UXP), which unfortunately does not have a solution at the moment.

Switching javascript.options.baselinejit or javascript.options.ion to false in about:config seems to get rid of the crash. Everything will of course be slower without JIT compilation, but if the OP needs/wants to try out the site in PM, it should be possible this way (I only tried on Windows, though).

Thanks, that observation is actually helpful in narrowing the issue down a little.

FTR if you have a choice of disabling baseline JIT and IonMonkey, always choose for disabling IonMonkey (baseline implies Ion, and disabling baseline disables both).

Good to know. I mean I figured that's probably the case, but I'm not familiar enough with these internals to start making suggestions about them.

Setting javascript.options.ion to false prevents crash on Linux, but even then, this particular website is unusable in Pale Moon (mouse control in 3D view does not work)

One problem at a time. For the moment the crash and a way to prevent it without complete screwing over of JS is the top priority.
