I'd love to know the regression-window for this, that stack trace is from before landing of bug 622482.

If the stack shown here is accurate, it seems strange that scaled_font is apparently NULL here: _cairo_dwrite_show_glyphs_on_d2d_surface(... scaled_font = 0x00000000`00000000 ...) ...even though a frame higher, it was non-NULL: _cairo_d2d_show_glyphs(... scaled_font = 0x00000000`0ffa8800 ...)

btw. i saw the same crashes on my thunderbird 3.3 alpha (nightly build). i did not debug it (because i have no 32bit windbg installed) but disabling d2d also helped. so i would assume that this is a core (gecko?) issue. cheers, raoul

Here is a crash report with this crash signature: bp-2543c7f6-f525-4b80-91f5-318422110117

so, i deleted gfx.direct2d.disabled and things work without any problem in: (means gfx.direct2d.disabled = false) minefield 4.012pre (2011-02-15) thunderbird/shredder: 3.3a3pre Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b12pre) Gecko/20110216 Thunderbird/3.3a3pre has this bug been fixed or has direct2d simply been globally disabled? thanks,

> has this bug been fixed or has direct2d simply been globally disabled? D2D/DW is now disabled with old versions of graphic drivers. Provide the graphic section from the about:support page to see if your issue has been fixed by that.

Intel GPUs are D2D block-listed when they are on computers with dual GPUs (see bug 628129). If you want HW acceleration enabled, use your ATI GPU (see bug 601079 for system requirement). I close this bug as "work for me".
