OS: Linux - 64bit (Ubuntu 20.04.2 LTS)
Package causes this problem:
(comes from system repo, not changed)
qt5-style-plugin-gtk2/focal,focal 5.0.0+git23.g335dbec-3ubuntu4 all
XnView MP fails to start on Ubuntu 20.04.2 LTS with QT_QPA_PLATFORMTHEME=gtk2.
Downloaded AppImage, chmod +x to make it executable. Running
Downloaded tgz (x64), extract and run ./xnview.sh
Effect: Program fails to start.
1. Download AppImage and tgz (x64)
2. Make AppImage executable with chmod +x
3. Run AppImage or xnview.sh in Terminal
Actual behaviour (bug): XnView doesn't start, shows following error messages:
Code: Select all
Cannot mix incompatible Qt library (5.15.1) with this library (5.15.6) Aborted (core dumped)
Must run xnviewmp with cleared QT_QPA_PLATFORMTHEME.
But it will be inconsistent with system theme. (dark mode, etc.)
Expected behaviour: Program starts without errors and runs with consistent native look-and-feel.
