Current LibreOffice master build used (as of commit 425a570a114d9a087e5320f071604f64d43fcec1) [To actually set up the icon-only task switcher, I had to: go to "System Settings" -> "Task Switcher", click the star icon to open the "Get Hot New Stuff" system settings module and install the "MediumRoundedDark" windows switcher; then select "Large Icons".] What Nate says about those icons being set in 'vcl/unx/generic/window/salframe.cxx' seems correct, **but** this is only relevant if the gen/x11 VCL plugin is used, which is not really what want to use anyway if you want a modern UI. :) If I use that VCL plugin (start LibreOffice with 'SAL_USE_VCLPLUGIN=gen ./instdir/program/soffice --writer', I can reproduce the issue, s. screenshot in <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151284" name="attach_151284" title="Screenshot when using gen/x11 VCL plugin">attachment 151284</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151284&action=edit" title="Screenshot when using gen/x11 VCL plugin">[details]</a>. However, if I use the gtk3 (SAL_USE_VCLPLUGIN=gtk3) or kde5 VCL plugin (default on KDE Plasma), the icon looks nice, s. <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151285" name="attach_151285" title="Screenshot when using kde5 VCL plugin">attachment 151285</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151285&action=edit" title="Screenshot when using kde5 VCL plugin">[details]</a>. As far as I can see, the icons are set in 'Qt5Frame::setIcon' using 'QWindow::setIcon' and it uses the icon from the icon theme [1], which for the writer case would be: QIcon aIcon = QIcon::fromTheme("libreoffice-writer"); The corresponding icon is located at '/usr/share/icons/breeze/apps/48/libreoffice-writer.svg'. If I open that icon using e.g. Inkscape, it looks the same as the icon in the task switcher in my screenshot. Since it's an SVG icon, there shouldn't be any issues with scaling etc. The behaviour is the same as with the attached little sample program ( <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151286" name="attach_151286" title="Small sample Qt application that shows the same behaviour">attachment 151286</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151286&action=edit" title="Small sample Qt application that shows the same behaviour">[details]</a> ). @Nate, or somebody else of those who are affected: Can you still reproduce this issue with a current master build of LibreOffice (available at and co-installable as described at [3])? If so: 1) Does it also happen with a clean user profile? (shouldn't play any role, but...) 2) What distro are you using? 3) What Plasma theme? 4) What happens when using the attached sample program (<a href="http://bugs.documentfoundation.org/attachment.cgi?id=151286" name="attach_151286" title="Small sample Qt application that shows the same behaviour">attachment 151286</a> <a href="http://bugs.documentfoundation.org/attachment.cgi?id=151286&action=edit" title="Small sample Qt application that shows the same behaviour">[details]</a>) instead of LibreOffice? 5) Can you attach an strace output? 6) Can you paste the version information from "Help" -> "About LibreOffice"? 7) Any other ideas what could be the reason?
