With D3D9 hardware accelleration enabled in Windows XP (using the latest nightlies from at least January 20th onward), when switching into Tab Candy mode, the thumbnails are missing all text in the web pages. Only the graphics appear. Likewise, the first tab opened will remain blank the entire time. Only subsequent tabs opened will display anything at all (and those will only have the graphics from the web pages displayed in the thumbnails... no text or Flash content). Will attach screen caps.
To clarify, in the case of "the first tab never displaying anything in its Panorama thumbnail" that isn't shown in my screen caps because I had all the tabs opened (without D3D9 accel enabled, took a screen-cap... turned on D3D9 accel, closed and reopened the browser and took a screen-cap). Seems like if tabs are loaded in from saved sessions on restart it's fine. Anyway, that probably deserves another bug. The purpose of this bug is just for the missing text (and it looks like textual HTML elements, like form fields, as well) with D3D9 on.
Example of the way Panorama thumbnails should look.
Here's the bug manifesting. Notice that all text and form elements from the prior image's thumbnails are missing. Only the static graphics remain.
Almost forgot. Adapter Description: Mobile Intel(R) 4 Series Express Chipset Family Adapter Drivers: igxprd32 Driver Version: 18.104.22.16803 Driver Date: 9-21-2010 GPU Accelerated Windows: 1/1 Direct3D 9
Just discovered that this also appears to be linked to the size of the thumbnails being drawn. When the thumbnails get below a certain size, the text comes back... will post a few more screen shots in a second.
Seems that once the thumbnails go below a certain threshold in size, the text and form elements actually come back (even with D3D9 accel enabled).
Exact same session as previous pic, but just resized the tab group box enough to enlarge the tab thumbnails slightly. Notice that all the text and form controls went away (it does seem that the site with the two tabs in the lower left is sort of still working though. Must be somehow related to something they're wrapping their content text in? www.tested.com is the site if at all interested).

Looks like it, yes. The width of the smaller thumbnails is in the mid 140s and the larger ones in the mid 150s.
yes I have this problem, the thumbnail generation is seriously overbright. I'm guessing they are being gpu calculated though, as hardware acceleration is turned on in Options, and I haven't adjusted any about:config entries on gfx/layers for testing new builds. The software rendered thumbs in your screenshot are better... I only get slightly better thumbnails when groups are resized smaller such that thumbnails are like 60px width.. after a certain point of resizing them larger they go really bright again. XpSP3, nvidia current latest drivers 480gtx Which about:config settings are need to be adjusted to disable all gpu hardware acceleration?
Will beta 10 be released without this being fixed? :(
(In reply to comment #11) > Will beta 10 be released without this being fixed? :( Yes. We don't have any fix for this in the pipeline, for that matter, as it stands. We'd love to have someone work on this. Marking P2. Windows is where the majority of our users are.

Is this a duplicate of bug 628173?
No, this is different. The tabs are not blurry in this bug: there's literally no text at all. The tab previews are blank sans the images.
Not sure of the level of this on the release radar, but I'm wondering if this could/should at least be set to "soft blocker"? Alternatively, should D3D9 just be disabled for release on Intel cards (at least the GMA4500HD) if this isn't fixed? As it stands, if the thumbnails aren't below 150px, then it makes using Tab Candy pretty useless unfortunately.
OK, let me guess. In bug 590373 we disabled D3D10 features when we detect that Intel drivers are mis-installed (igl...dll version different from driver version in the windows registry). So now Firefox is using D3D9 layers instead, which explains why you guys with D3D10-capable chips are using D3D9 layers. It just seems that we have to disable D3D9 layers too in this case. Anyone who can reproduce this, can you please check the version of your igd10umd32.dll ? Is it the same as the driver version reported in about:support?

The usefulness of this patch still depends on replies to my question in previous comment about DLL version.
*oh* this is Windows XP so no Direct3D 10. Can you then please still check your DLL versions, except I'm not sure what DLL this is. Anything starting in igd... may be interesting. Compare to Driver Version reported in about:support.
The file version reported by about:support is: igxprd32: 22.214.171.12403 There does appear to be two Intel GL related DLLs under the XP system32 folder (with differing versions): ig4icd32.dll: 126.96.36.19903 iglicd32.dll: 188.8.131.5226 But I'm guessing those should be unrelated to this. As for the D3D files corresponding to the one mentioned in about:support, system32 contains the following: igxpdv32.dll igxpdx32.dll igxpgd32.dll igxprd32.dll All of these have the matching 184.108.40.20603 version number. Anything else to check?
Indeed, iglicd32.dll is the OpenGL driver so it's not relevant here. Can you please copy to clipboard your about:support info and paste here the Graphics section?
(I mean, the info in comment 4 is missing the Device ID)
FYI, that file that about:support says it's using is listed in the description as "Intel Graphics 2D Rotation Driver". Doesn't seem to mention anything specifically on D3D9. Also, from what I could find, there were no DLLs starting with "igd" under the system32 folder. I'll search elsewhere.
Device ID is 2a42.
Nevermind about igd*, I just don't know my Windows XP well. OK, device 2a42 is usual HD4500.
CC'ing some gfx guys.
DXDiag also identified: Main Driver: igxprd32.dll so looks like that's the only pertinent one from what I can tell. The file isn't WHQL signed, but other than that everything passes fine (Direct Draw and Direct3D tests, DX7-9). It also states that the "Mini VDD" is igxpmp32.sys. Checking this file under system32/drivers, it too has the exact same version number.
This is not just Intel, I have ATI Radeon HD 4600 and I have this bug. Driver is ati2dvag 8.812.0.0 To my knowledge, this bug affects anybody on Windows XP with acceleration turned on.
Thanks Timofei, this is very useful to know. Bas, can you have a look at this? This looks like a legit bug in D3D9 layers, happening on ATI and Intel drivers.
This maybe a duplicate of 628173
Per comment 30, looking at the screenshots in bug 628173, it appears that the text content is missing in there as well for anything above 150px (just wasn't specifically noted... only the blurriness was). As long as that bug is being handled, please feel free to mark this as a dupe.
