713130 - webgl test case freezes machine (and seems to overflow GPU memory)

Status: RESOLVED INCOMPLETE

(Core :: Graphics, defect)

Description

[Andreas Gal :gal]

This bug was discovered and reported by Michael Bebenita.

http://mbebenita.github.com/Broadway/benchmarks.html

Michael: Click on Texture Upload x 1000 (Variable Size). Basically, I'm uploading lots of large textures (4000x4000). It was crashing my MacBook Air only under Chrome Caray, I cannot reproduce it on windows.

The test case just crashed my MBP with Firefox Nightly (using integrated gfx). My machine froze hard (I had to reset).

Do not open this bug until we have confirmation from the Chrome team how this affects them.

argh. This is very similar to allocating many large JS arrays, except that saturating video memory can have worse effects than saturating general memory on some systems, notably on Mac as you report.

Does the JS engine do anything to prevent scripts from saturating general memory by creating many large arrays?

Nope, just OOM.

The URL doesn't work any more and this was filed a long time ago.
