--- Comment #1 from Illia <[email protected]> --- I'm also seeing something very similar on Ubuntu 26.04, with kdiff version 1.12.4-1. If I set `CreateBakFiles=false` in `~/.config/kdiff3rc` and then run `git mergetool --tool kdiff3` I actually do see a window appear. But there is no content drawn in the window. So it is unusable. I can resize the window, and it just shows garbage from the pixels it overlaps. Sending SIGTERM safely terminates kdiff3. Changing the setting back fixes the issue. I'm running GNOME with a custom window manager. kdiff3 is installed from the Ubuntu package repository: Package: kdiff3 Version: 1.12.4-1 Priority: optional Section: universe/kde Origin: Ubuntu Maintainer: Ubuntu Developers <[email protected]> Original-Maintainer: Debian KDE Extras Team <[email protected]> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 4,760 kB Depends: kio6, libc6 (>= 2.34), libgcc-s1 (>= 3.3.1), libicu78 (>= 78.1-1~), libkf6configcore6 (>= 6.2.0~), libkf6configwidgets6 (>= 6.0.0), libkf6coreaddons6 (>= 6.2.0~), libkf6crash6 (>= 6.2.0~), libkf6i18n6 (>= 6.2.0~), libkf6kiocore6 (>= 6.8.0), libkf6kiowidgets6 (>= 6.2.0~), libkf6widgetsaddons6 (>= 6.2.0~), libkf6xmlgui6 (>= 6.2.0~), libqt6core6t64 (>= 6.10.2), libqt6gui6 (>= 6.9.1), libqt6printsupport6 (>= 6.6.0~), libqt6widgets6 (>= 6.6.0~), libstdc++6 (>= 14) Recommends: kdiff3-doc Homepage: https://kde.org/applications/development/kdiff3 Download-Size: 971 kB APT-Manual-Installed: yes APT-Sources: http://us.archive.ubuntu.com/ubuntu resolute/universe amd64 Packages -- You are receiving this mail because: You are watching all bug changes.
