66862 2011-08-24 10:18:19 -0700 [chromium] Renderer crashes if compositor runs out of texture memory 2011-08-24 15:10:14 -0700 1 1 1 Unclassified WebKit New Bugs 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 0 husky webkit-unassigned enne husky jamesr nduca webkit.review.bot oldest_to_newest 456164 0 husky 2011-08-24 10:18:19 -0700 To reproduce: load http://diden.net/test/tex.html and move the slider to the right. The renderer reliably crashes at around 60. (That might be because of the hard-coded texture limit of 64MB. The usage reported by the page may not be accurate, though, because of tiling.) Possibly related to TextureManager refactoring? https://bugs.webkit.org/show_bug.cgi?id=64772 The old behavior was just to skip drawing some layers, but that wasn't really ideal either. 456175 1 husky 2011-08-24 10:31:47 -0700 It's an assert: ./gpu/command_buffer/client/../client/gles2_implementation_autogen.h(287): GPU_DCHECK(textures[i] != 0 (0)) failed. 456234 2 jamesr 2011-08-24 11:18:14 -0700 Stack? 456260 3 105029 husky 2011-08-24 11:36:46 -0700 Created attachment 105029 gdb backtrace Looks like we're just deleting 0? I think that's kosher so maybe the DCHECK isn't needed. No crash in release builds. 456317 4 jamesr 2011-08-24 12:44:20 -0700 Yeah, I've been assuming that deleting texture 0 is safe. It's quite easy to avoid calling deleteTexture() on zero if the underlying stack is unhappy with it, though. 456424 5 105072 husky 2011-08-24 14:48:05 -0700 Created attachment 105072 Patch 456430 6 husky 2011-08-24 14:48:57 -0700 Turns out we got stricter back in June - http://code.google.com/p/chromium/issues/detail?id=85268 456435 7 105072 jamesr 2011-08-24 14:52:56 -0700 Comment on attachment 105072 Patch Ah, OK.
