Firstly, I didn't meet window missing bug with the ppa version till now, but I'm not sure whether it will happen several days later (Just like what I had said at #43, it took around 4-5 days to produce one window missing ..)
Secondly, as for the new issue (title rendering problem), I can provide the following information: My Physical PC: $ lspci | grep NV -i 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 850M] (rev a2) $ lsmod | grep nou nouveau 1495040 0 mxm_wmi 16384 1 nouveau ttm 98304 1 nouveau i2c_algo_bit 16384 2 i915,nouveau drm_kms_helper 139264 2 i915,nouveau drm 360448 11 ttm,i915,drm_kms_helper,nouveau wmi 20480 3 msi_wmi,mxm_wmi,nouveau video 40960 3 i915,msi_wmi,nouveau ------------------------------------------------- Open gnome-terminal (or firefox / nautilus / gedit or any other apps that can support multi tab-pages), and confirm that 1、Makeing the window maximized 2、Using Composite Manager Then, Ctrl + Shift + T to generate a new tab page, then switching it will leave the edge shadow of each charactor in the title unerased, like what I had shown in the above image. I have tested that, 1、without composite manager, this issue (edge of each title charactor is unerased) doesn't happen, even when the window is maximized. 2、If the window is not maximized, this issue also doesn't happen, even when Composite Manager is enabled. 3、this issue doesn't happen inside my created virtualbox, even if this virtualbox runs on my current metacity session, with composite manager enabled. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1538111 Title: untraceable serious bug in metacity 3.18 Status in metacity package in Ubuntu: In Progress Bug description: Ubuntu 16.04 LTS uses 3.18 version of gnome metacity. When doing lots of mess work in Desktop (such as open desktop window, sudo window, dragging window, and so on), "!! WHEN CLICKING CLOSE BUTTON OF A CERTAIN WINDOW !!", there is "small possibility" for metacity to get out of work --> Many windows are disappeared, with only nautilus desktop background and gnome-panel on screen. "Live Window List" still exists in gnome-panel, but no matter doing what (such as open new application from gnome-menu or use Alt+Tab to switch window), none of live windows can be displayed. So the only way is to switch to tty1 using Ctrl+Alt+F1, and executing "DISPLAY=:0 metacity -c --replace", then all windows came back. Till now, I meet this bug every day, but still not sure how to reproduce it bug. I think you should trace what the metacity do when clicking "close button" that makes all windows to be disappeared. Thanks.
