I've recently switched to Manjaro Linux running KDE Plasma 5 and ran into some problems with the Steam Linux version 1.6.0. The Problem Summary Basically, RPG Maker is using its own libQt5Core.so.5 library while Plasma 5 is using a newer version. When I go to open a new project, the open dialog causes a crash because MV is opening my system file dialog which uses the latest version and you can't mix qt versions without problems. The Logging Process So as a fresh installation of both steam and RPG Maker MV everything seems to work fin, the MV editor opens up fine, but the open project is what causes the crash, I attached the full terminal log in a txt document. The core of the errors are shown here Editor Starting: Upon opening the "Open Project" dialog: Then upon crash, I get this message: And the (core dumped) log which is what is logged to Linux after it crashes is shown here. I tried creating a symlink to override the Mv version of libQt5Core to use my system's version but this caused more issues. I logged via terminal after the symlink I have also attempted to change the RPG Maker MV.sh script to point the LD_LIBRARY_PATH variable to my /usr/libs/ directory LD_LIBRARY_PATH=/usr/libs/ The Solution Process' Current Workaround: Use different Desktop Enviroment xfce4 runs MV well. It would seem someone had this same problem and tried to make the developers aware of it but has gone unnoticed. Same issue: https://forums.rpgmakerweb.com/inde...ux-open-folder-doesnt-work.76302/#post-716482 I started a topic over at the Manjaro forums to see if we can come up with a workaround as well as figure out the core of the problem. Manjaro Forums Thread: https://forum.manjaro.org/t/rpg-maker-mv-dialog-window-crash-libqt5core-so-5/36011/3 Personally, I would love to work with the developers and community to get this updated in the next main MV Editor update and figure out a workaround in the meantime, other than a different desktop environment. I would love to hear your take on it, maybe you have a solution in the works, maybe you plan on updating the QT libraries included with MV, either way, I would love to hear from you and get this figured out.
