Description: At some time in the past (when the Sidebar was first appearing), Writer spent an enormous amount of time redrawing the screen over and over whenever the window was resized horizontally. I was unable to locate the original bug report, but I did mention noticing that the problem had been corrected when I said the following while posting bug #99829: ****************BEGIN QUOTE: Just got to use the newly downloaded LibreOffice: Version: 5.1.3.2 Build ID: 1:5.1.3~rc2-0ubuntu1~trusty1 CPU Threads: 4; OS Version: Linux 3.19; UI Render: default; Locale: en-US (en_US.UTF-8) First thing I noticed was that one can now grab the right screen edge to resize the window without the SideBar stretching ever-so-slowly to catch up. Kudos for the speed-up! ****************END OF QUOTE With the most recent update (through the ppa "http://ppa.launchpad.net/libreoffice/libreoffice-5-0/ubuntu xenial main") the painfully slow horizontal stretching is now back. I now have: Version: 5.2.3.2 Build ID: 1:5.2.3~rc2-0ubuntu1~xenial1 CPU Threads: 4; OS Version: Linux 4.4; UI Render: default; Locale: en-US (en_US.UTF-8); Calc: group As I said earlier, my recollection is that the "slow stretching" originally had to do with the Sidebar (at the time listed as "experimental"). Something has regressed between 5.1.3.2 (when I reported it "fixed") and now (5.2.3.2); since I've had the ppa active for a while, I suspect this very last update. I didn't notice this regression immediately, since I have been avoiding LO when I don't need it, but I'm pretty sure I used Writer often enough to have noticed it before this update. I believe this is NOT related to bug #99153 - even though I use 64 bit Ubuntu, I never noticed that issue. Bug #99702 also seems to report similar issue(s) but, again, it's different enough that it's hard to say. Bug #101213 seems to be related mostly to spreadsheets, but doesn't sound the same to me either. Steps to Reproduce: 1. With Sidebar displayed, resize the screen. 2. That's it. 3. Same problem existed earlier - got fixed in 5.1.3.2 - came back with 5.2.3.2 Actual Results: Resize seems to redraw the screen for every pixel, blinking until it gets to where it needs to be. Expected Results: Just resized normally. Reproducible: Always User Profile Reset: No Additional Info: User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0
Did you play with gtk2 and gtk3 backends? You should try that: 1/ install the package libreoffice-gtk2 if it is not already done 2/ install the package libreoffice-gtk3 if it is not already done 3/ in the terminal: $ export SAL_USE_VCLPLUGIN="gtk" $ libreoffice or $ export SAL_USE_VCLPLUGIN="gtk3" $ libreoffice Do you have the same problem with both ? Set status to NEEDINFO, please set it back to UNCONFIRMED once requested informations are provided. Best regards. JBF
Thanks for the quick reply ... libreoffice-gtk and libreoffice-gtk2 were already installed, but libreoffice-gtk-3 was not. It was, however, present on my system and listed (but unchecked) in Synaptic. After installing it, Writer's horizontal scrolling now responds as it used to. Does that indicate a packaging problem? (BUT: See error message below) If there is a packaging problem, does the "ubuntu1~trusty1" in the Build ID ("Build ID: 1:5.1.3~rc2-0ubuntu1~trusty1") indicate that the issue might be exclusive to Ubuntu? Should I file a bug report with Canonical, or are all the ppa packages done by TDF? Another observation: After the installation of libreoffice-gtk-3 completed, Synaptic displayed an error message saying: Synaptic finishes with an error: W: Can't drop privileges for downloading as file '/root/.synaptic/tmp//tmp_sh' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied) I have no idea at all what that means, as synaptic requires the password to open. I did notice that there are two slashes in the file name, though. Could it be that the packaging contained the libreoffice-gtk-3 but it didn't get installed because of whatever issued the error message above? In summary, this bug should probably be marked as "solved" or "closed" or whatever, but the fact that I experienced the issue in the first place seems to indicate that there is some other issue lurking about. Again, thanks for the response and, if I need to file some bug with Ubuntu about the packaging, please let me know. --Frank

Ok, we have a workaround. That said gtk3 backend is the default in Ubuntu 16.10. For me it is a duplicate of bug 99153. *** This bug has been marked as a duplicate of bug 99153 ***
