Black spots appearing on page while scrolling
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release) Build ID: 20130905030206 Steps to reproduce: Browse normally, and scroll down pages. Actual results: Sometimes, upon scrolling (the effect is seemingly random, although it tends to happen in loose clusters), black spots (rectangles of 3x6 pixels) appear on the page. - This does not happen on chrome. - A spot disappears when it scrolls out of view or when it "hits" position:fixed elements on the page. - Spots only appear while scrolling, never when stationary. - All spots disappear when the window loses focus, e.g. when alt-tabbing or changing workspace or clicking another application. (This makes them quite hard to capture.) Reproduced: (and with combinations of the below) - on Firefox 26.0a1 (2013-09-05) - on Firefox 23.0.1 - in safe mode - with a clean profile - with hardware acceleration disabled Graphics: Adapter Description: Intel Open Source Technology Center -- Mesa DRI Intel(R) Ivybridge Mobile Device ID: Mesa DRI Intel(R) Ivybridge Mobile Driver Version: 3.0 Mesa 9.2.0 GPU Accelerated Windows: 0/1 Basic Vendor ID: Intel Open Source Technology Center WebGL Renderer: Intel Open Source Technology Center -- Mesa DRI Intel(R) Ivybridge Mobile windowLayerManagerRemote: false AzureCanvasBackend: cairo AzureContentBackend: none AzureFallbackCanvasBackend: none AzureSkiaAccelerated: 0 Expected results: No spots should appear on the page!
I have this issue too. Seems like it is related to the XF86 Intel video driver: https://bugs.freedesktop.org/show_bug.cgi?id=68410 This happens on random pages.
Hi Happened to me too on Firefox 25, both on Arch linux and Gentoo. On Intel graphics and x64 Intel Haswell However - _other browser works fine_, tested Epiphany. I can help with some testing/debugging if needed
I have white ones: http://www.transformerforums.com/forum/asus-transformer-book-t100-help/41722-strange-dots-only-firefox.html Asus T100
Yay, I have the same bug with FireFox 32 on Gentoo Linux. I'm also using a system with Intel graphics. I would suspect it's either a bug in the Intel driver or a Mesa problem.
The issue seems to be Intel driver related. Here is a discussion of the issue including some workarounds: https://bbs.archlinux.org/viewtopic.php?id=169449
Issue disappeared after upgrading the Intel driver to 2.99.916
