Status: RESOLVED DUPLICATE of bug 646229

(Core :: Graphics: CanvasWebGL, defect)

Description

[Petr Sloup]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.127 Safari/534.16
Build Identifier: Mozilla Firefox 4 RC1

ANGLE project maps webgl texture coordinates to d3d coordinates, which has Y-axis flipped (http://code.google.com/p/angleproject/source/detail?r=536) - this introduced a bug when using gl.texSubImage2D to upload the texture to VRAM.

This bug has been fixed in ANGLE project for a long time: http://code.google.com/p/angleproject/source/detail?r=551 but Firefox 4 seems to be still using revision 550.

Reproducible: Always

Actual Results:  
Application on https://developer.mozilla.org/en-US/demos/detail/webgl-earth/launch does not work because of this bug (some parts of the globe are not visible), but it works ok if I set webgl.prefer-native-gl to true.


It seems to be working OK in Minefield 4.0b13pre (2011-03-09).

Well, we are indeed using r550, we'll sync again soon anyway.

Hope this happens before final release of FF4, because it contains a lot of other bugfixes as well..

Note that r551 in particular has been rolled in to what will become Firefox 4.0.1 too! :) (This happened in bug 649233.)
