I have my NVidia card configured to use two separate X screens, which appear as :0.0 (laptop internal panel) and :0.1 (external LCD attached through HDMI-to-DVI cable). When I run Opera on :0.1, enable plugins, visit Youtube, and load a movie, Opera's CPU usage hits 100% and the movie doesn't play (Opera is still navigable, though: changing tabs works, as does loading a new page or closing the tab, and navigating away from the movie brings CPU usage back down to normal levels). Viewing the movie in Firefox on screen :0.1 or in Opera on screen :0.0 both work fine. Reproducible: Always Steps to Reproduce: The video card is a GeForce GTS360M. # emerge --info Portage 2.1.8.3 (default/linux/amd64/10.0, gcc-4.4.4, glibc-2.11.2-r0, 2.6.35-gentoo-r4 x86_64) ================================================================= System uname: Linux-2.6.35-gentoo-r4-x86_64-Intel-R-_Core-TM-_i7_CPU_Q_720_@_1.60GHz-with-gentoo-1.12.13 Timestamp of tree: Sun, 07 Nov 2010 02:45:01 +0000 app-shells/bash: 4.1_p7 dev-java/java-config: 2.1.11 dev-lang/python: 2.6.5-r3, 3.1.2-r4 dev-util/cmake: 2.8.1-r2 sys-apps/baselayout: 1.12.13 sys-apps/sandbox: 2.3-r1 sys-devel/autoconf: 2.13, 2.65-r1 sys-devel/automake: 1.9.6-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.4.4-r2 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.10 sys-devel/make: 3.81-r2 virtual/os-headers: 2.6.30-r1 ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="* -@EULA dlj-1.1 sun-bcla-java-vm AdobeFlash-10.1" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=core2 -msse4 -mcx16 -mpopcnt -msahf -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/eselect/postgresql /etc/fonts/fonts.conf /etc/gconf /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-march=core2 -msse4 -mcx16 -mpopcnt -msahf -O2 -pipe" DISTDIR="/var/cache/distfiles" FEATURES="assume-digests distlocks fixpackages news parallel-fetch protect-owned sandbox sfperms splitdebug strict unmerge-logs unmerge-orphans userfetch" GENTOO_MIRRORS="http://gentoo.chem.wisc.edu/gentoo ftp://gentoo.arcticnetwork.ca/pub/gentoo ftp://ftp.snt.utwente.nl/pub/os/linux/gentoo" LANG="en_CA.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="en en_CA" MAKEOPTS="-j8" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/lib/layman/sunrise /usr/local/portage" SYNC="rsync://rsync.ca.gentoo.org/gentoo-portage" USE="X a52 aac acpi aio alsa amd64 bzip2 cairo caps cdda cddb cdinstall cdio cli cups custom-optimization cvs cxx dbus dillo double-precision dri dvd faac faad fat ffmpeg fftw flac fortran gcrypt gif gimp glade glibc-omitfp gmp gnutls gtk hal hou hpn idn imap iphone java java6 jce joystick jpeg laptop libsamplerate mercurial mikmod mmx modules mp3 mpeg multilib multiuser ncurses nls nntp nowin nptl nptlonly ntfs ntp offensive ogg opengl openmp pam pdf plotutils png pppd qq readline scanner sdl session sou sparse spell sse sse2 ssse3 startup-notification stream subversion svg symlink sysfs taglib theora thunar timidity truetype unicode usb v4l2 videos vim-syntax vorbis xinerama xorg xscreensaver xulrunner xv xvid xvmc zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="evdev synaptics" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en en_CA" PHP_TARGETS="php5-2" QEMU_SOFTMMU_TARGETS="i386 x86_64" RUBY_TARGETS="ruby18" SANE_BACKENDS="plustek" USERLAND="GNU" XFCE_PLUGINS="menu" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LC_ALL, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
So with Firefox, running on either screen is OK, and with Opera, running on the second screen goes bad? As you may know, Opera is closed source, so please report this upstream. Also, try an opera-11 build to see if it's fixed there.
Opera 11 doesn't fix this. I sent the report upstream, with the usual Opera policy of "submit the problem report form and not get anything useful to track the bug with, no ticket number, etc." We'll see what happens. No point keeping this open anyway.
