Host: {{{ Windows 8.1 16GB RAM NVIDIA GTX 860M (dedicated GPU) Intel HD 4600 (integrated GPU) VirtualBox 4.3.20r96997 }}} Guest: {{{ Debian 8 (testing) quite fresh installation 3D acceleration enabled }}} Issue: It looks everything work fine....but after some using of Totem video player, window decoration crashes (see the attached screenshot): for example 1. If I select menu->properties during video playback, its window is not visible because video rectangle remain ""on top"", while the properties window lies correctly above the title bar. 2. If I open and close several video files, suddenly window decoration crashes. Buttons are not drawn (even the date and the clock) and there are white or gray rectangles in their place. If I restart gnome 3 (alt+F2 then ""r""), some buttons are still not clickable, i.e. poweroff button, some other are missing (I suppose it is a gnome 3 behaviour after video capabilities have been switched from 3D to 2D). I have to reboot from a terminal (TTY). Xorg logs are clean, while virtualbox guest logs show GuestAdditions errors: (full log is attached) {{{ 00:07:49.644926 Guest Additions capability report: (0x5 -> 0x1) seamless: yes, hostWindowMapping: no, graphics: no 00:07:50.050200 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=0000000000000000 w=720 h=400 bpp=0 cbLine=0x0, flags=0x1 00:07:50.050224 UIFrameBuffer::RequestResize: Screen=0, Format=0, BitsPerPixel=0, BytesPerLine=0, Size=720x400, Sending to async-handler.. 00:07:50.050288 UIFrameBufferQImage::resizeEvent: Format=0, BitsPerPixel=0, BytesPerLine=0, Size=720x400 00:07:50.050301 UIFrameBufferQImage::resizeEvent: Resizing to FALLBACK buffer due to format is invalid.. 00:08:00.952341 Guest Additions capability report: (0x1 -> 0x0) seamless: no, hostWindowMapping: no, graphics: no 00:08:00.956122 Guest Log: VBoxGuestCommonIOCtl: HGCM_CALL: Invalid handle. u32Client=13 00:08:00.956161 Guest Log: VBoxGuestCommonIOCtl: HGCM_CALL: Invalid handle. u32Client=13 }}}",defect,new,3D support,VirtualBox 4.3.20,,"opengl, 3d, acceleration, guest, additions",,Linux,Windows
