Package: iceweasel Version: 38.2.0esr-1~deb8u1 Severity: important Dear Maintainer,
after upgrading to Iceweasel version 38.2.0 (previous versions of Iceweasel were working fine!) there is a bug with Multi-Monitor setup and Iceweasel. Bug Description: Opening a popup menu (like the File Menu or Bookmark Menu) leads to opening the Menu on the second screen while the iceweasel window is displayed on the first (primary) screen. Expected is that the popup menu is displayed near the mouse pointer and near the iceweasel window not on a completely different screen. How to trigger: Tracking down the bug reveals that it has to do with configuration of option: layout.css.devPixelsPerPx Setting the value of layout.css.devPixelsPerPx in about:config to a value below 1.0 triggers the problem always! Even with a virgin iceweasel profile and _NO_ add-ons installed, I tested this explicitely! Setting the value of layout.css.devPixelsPerPx in about:config to a value -1.0 or bigger than 1.0 prevents the bug, but iceweasels representation of websites and the UI is way to large. Remark: * Setup of Multi-Monitor is done by: xrandr --output eDP1 --primary --auto --output HDMI1 --auto --below eDP1 --dpi 85 Regards -- Package-specific info: -- Extensions information Name: Bluhell Firewall Location: ${PROFILE_EXTENSIONS}/{6BB5760D-F97E-421B-AF5B-8457A90C3CED}.xpi Status: enabled Name: Classic Theme Restorer (Customize UI) Location: ${PROFILE_EXTENSIONS}/classicthemeresto...@arist2noia4dev.xpi Status: enabled Name: Compact Menu 2 Location: ${PROFILE_EXTENSIONS}/{57068FBE-1506-42ee-AB02-BD183E7999E4}.xpi Status: enabled Name: Default theme Location: /usr/lib/iceweasel/browser/extensions/{972ce4c6-7e08-4474-a285-3208198ce6fd} Package: iceweasel Status: user-disabled Name: Firesizer Location: ${PROFILE_EXTENSIONS}/{04426594-bce6-4705-b811-bcdba2fd9c7b}.xpi Status: enabled Name: Ghostery Location: ${PROFILE_EXTENSIONS}/fire...@ghostery.com.xpi Status: enabled Name: LittleFox theme Location: ${PROFILE_EXTENSIONS}/{29852C08-1E91-4889-A6BF-C77F91D6A8F3}.xpi Status: enabled Name: MicroFox theme Location: ${PROFILE_EXTENSIONS}/{403304EE-066A-4a2a-8F41-F12028480A0A}.xpi Status: user-disabled Name: NoScript Location: ${PROFILE_EXTENSIONS}/{73a6fe31-595d-460b-a920-fcc0f8843232}.xpi Status: enabled Name: ScrapBook Location: ${PROFILE_EXTENSIONS}/{53A03D43-5363-4669-8190-99061B2DEBA5}.xpi Status: enabled Name: SQLite Manager Location: ${PROFILE_EXTENSIONS}/sqlitemana...@mrinalkant.blogspot.com.xpi Status: enabled Name: Stylish Location: ${PROFILE_EXTENSIONS}/{46551EC9-40F0-4e47-8E18-8E5CF550CFB8}.xpi Status: user-disabled Name: Tab Mix Plus Location: ${PROFILE_EXTENSIONS}/{dc572301-7619-498c-a57d-39143191b318}.xpi Status: enabled -- Plugins information Name: Shockwave Flash (11.2.202.508) Location: /usr/lib/flashplugin-nonfree/libflashplayer.so Status: enabled -- Addons package information ii iceweasel 38.2.0esr-1~ i386 Web browser based on Firefox -- System Information: Debian Release: 8.1 APT prefers stable APT policy: (990, 'stable'), (500, 'stable-updates'), (500, 'oldstable') Architecture: i386 (i686) Kernel: Linux 3.16.0-4-686-pae (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages iceweasel depends on: ii debianutils 4.4+b1 ii fontconfig 2.11.0-6.3 ii libasound2 1.0.28-1 ii libatk1.0-0 2.14.0-1 ii libc6 2.19-18 ii libcairo2 1.14.0-2.1 ii libdbus-1-3 1.8.18-0+deb8u1 ii libdbus-glib-1-2 0.102-1 ii libevent-2.0-5 2.0.21-stable-2 ii libffi6 3.1-2+b2 ii libfontconfig1 2.11.0-6.3 ii libfreetype6 2.5.2-3 ii libgcc1 1:4.9.2-10 ii libgdk-pixbuf2.0-0 2.31.1-2+b1 ii libglib2.0-0 2.42.1-1 ii libgtk2.0-0 2.24.25-3 ii libhunspell-1.3-0 1.3.3-3 ii libpango-1.0-0 1.36.8-3 ii libsqlite3-0 3.8.7.1-1+deb8u1 ii libstartup-notification0 0.12-4 ii libstdc++6 4.9.2-10 ii libx11-6 2:1.6.2-3 ii libxcomposite1 1:0.4.4-1 ii libxdamage1 1:1.1.4-2+b1 ii libxext6 2:1.3.3-1 ii libxfixes3 1:5.0.1-2+b2 ii libxrender1 1:0.9.8-1+b1 ii libxt6 1:1.1.4-1+b1 ii procps 2:3.3.9-9 ii zlib1g 1:1.2.8.dfsg-2+b1 Versions of packages iceweasel recommends: ii gstreamer1.0-libav 1:1.4.5-dmo1 ii gstreamer1.0-plugins-good 1.4.4-2 Versions of packages iceweasel suggests: ii fonts-mathjax 2.4-2 pn fonts-oflb-asana-math <none> pn fonts-stix | otf-stix <none> ii libcanberra0 0.30-2.1 pn libgnomeui-0 <none> ii libgssapi-krb5-2 1.12.1+dfsg-19 pn mozplugger <none> -- no debconf information
