The above does not happen with hardware acceleration off. Reproducible: Always Steps to Reproduce: 1. Install the Versions extension. 2. Create a list of about 50+ entries. 3. Turn on hardware acceleration. 4. Launch a scan from the add-on bar icon. Actual Results: High CPU usage and general unresponsiveness of firefox. Expected Results: Load the list in a few seconds, not hanging firefox.

There you go - http://img5.imageshack.us/img5/7311/graphicsl.png Thanks.
Adam, which extension is "Versions"? I can't seem to find anything called that on addons.mozilla.org. How does one create that list of 50+ entries? Something worth checking: Is the problem gone if you disable D2D but leave layers acceleration? This could be bug 593812 if so....
Hello Boris, The extension in mention is https://addons.mozilla.org/en-US/firefox/addon/3830/ The list is the list that is used by the extension to detect changes in webpages, it is located in the profile folder under \Versions, specifically my list can be found in http://www.text-upload.com/read.php?id=25170&c=9504310 , just copy and paste into a new .list file. As for your offer, I set "gfx.direct2d.disabled" to true and made sure "layers.accelerate-all" is set to true as well. Suppose this is what you meant, than the problem is indeed gone in that case. Thanks, Adam.

Depends on: 593812
Ever confirmed: true
Summary: High CPU usage when loading a list in the Versions extension using hardware acceleration → High CPU usage when loading a list in the Versions extension using d2d
(In reply to comment #5) > Hmm. This doesn't seem to use a tree... But the widgets it creates use a lot -moz-border-colors rules, which Bas identified as the main cause of bug 593812. (See skin/wfx_versions_custom.css) I can reproduce this using the original XPI. I furthermore tried removing all the -moz-border-colors stuff, with the result that the thing loaded much much faster. So I guess this is indeed very similar to bug 593812, if not entirely the same.
Just a quick note, when loading the exact same list for editing purposes, I experience no lag at all, everything runs smooth as it should be. This is done by opening the extension options window, clicking the edit button in the bottom left and edit again.
