(Switching back to proprietary nVidia driver) results in (graphic corruption after resume from suspend)
However it seems there might be some issue related to how shadows are rendered. Using nouveau, there are no shadows, and windows have borders instead of being borderless with shadows. I'm not familiar with: how the shadows are rendered, but there might be some bug with shadow rendering path. ** Attachment added: "Graphic corruption around windows" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1576228/+attachment/4685624/+files/Screenshot%20from%202016-06-17%2018-33-08.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1576228 Title: Black borders around all windows Status in xorg package in Ubuntu: New Bug description: There seems to be a bug somewhere in [ kernel OR xorg OR nvidia proprietary driver ] in the display stack. After the laptop ( dell XPS L501X ) resumes from suspend there are wide black borders around all windows with close/minimize/maximize buttons blacked out. [ image attached: black border on all windows ] It occurs inconsistently, as it doesn't happen every time the computer resumes. ( Slight possibility that it usually occurs after long suspend, i.e. resuming after long time ). ================================================================================= Also there seems to be certain amount of performance degradation as if the graphics driver was running at half-strength ( and I don't mean software-only rendering, neither do I mean switch over to nouveau open source driver ) The "nVidia X Server Settings" app suggests its in maximum performance mode. ================================================================================== Adhoc Workaround: switch display layout ( I have an external monitor/TV attached to HDMI port ) changing anything such as arrangement or resolution of the displays, etcetera... corrects the black border issue ( and also possibly performance issue ) This bug has been present in Ubuntu 14.04, 15.04, 15.10 and now in 16.04 as well. ( It was probably present before that as well ) ================================================================================== p.s. this is only partial duplicate of black border issue as the black borders appear on every window, not just windows with new header bars or client side decoration...
