Update: Fixing the file name fixes both the taskbar icon and task switcher icon.<\/p>\n\n\n\n
After a recent bout of updates on my Kubuntu desktop, I noticed that msedge web apps always show the Wayland Icon for the running window. This is pretty annoying – turns out the problem is a mismatch of msedge will store the application files under From my investigation, it looks like the StartupWMClass<\/code> in the application files – the better fix is renaming the file to match the StartupWMClass<\/code> instead.<\/p>\n\n\n\n${HOME}\/.local\/share\/applications<\/code>. The files will be msedge-*.desktop<\/code>. You can update the StartupWMClass<\/code> manually by finding out what the right value is – to do this, you run the web app, open KDE > Settings > Search > Window Rules > + Add New > Detect Window Properties<\/code> and click on the web app window. This should show you all relevant properties of the window including Window Class<\/code> which is what we want to set as StartupWMClass<\/code> value in the msedge-*.desktop<\/code> file.<\/p>\n\n\n\nStartupWMClass<\/code> for msedge applications as of this writing is simply msedge-_<rest of filename><\/code>. So here’s a simple script that should fix all your msedge-*.desktop<\/code> files so they have the right icons in the task bar and switcher, get grouped correctly when running under KDE Plasma:<\/p>\n\n\n\n#!\/bin\/bash\n\napp_dir=\"${HOME}\/.local\/share\/applications\"\napp_backup_dir=\"${HOME}\/msedge-apps\"\n\nif [ ! -d \"${app_backup_dir}\" ]; then\n echo \"Creating ${app_backup_dir}\"\n mkdir -p \"${app_backup_dir}\"\nfi\n\nfor file in \"$app_dir\"\/msedge-*; do\n filename=$(basename \"$file\")\n\n if [[ \"$filename\" == msedge-_* ]]; then\n echo \"Skipping already fixed file: $filename\"\n continue\n fi\n\n echo \"Fixing ${filename}\"\n cp \"${file}\" \"${app_backup_dir}\/\"\n rest=\"${filename#msedge-}\"\n rest=\"${rest%%.*}\"\n new_filename=\"msedge-_${rest}.desktop\"\n mv \"${file}\" \"$app_dir\/${new_filename}\"\ndone\n<\/code><\/pre>\n\n\n\n
