I installed Lubuntu 18.04 LTS on VirtualBox, and I met similar issue. The text messages on gajim chat window were messy. GTK didn't seem to refresh the window and kept previous text overlapped on the window.
I found a discussion (in Chinese) here, they found an workaround solution - changing desktop theme: https://www.ubuntu- tw.org/modules/newbb/viewtopic.php?topic_id=108158&forum=2&post_id=360960 My input method was changed to gcin. Other than that, LXDE related settings were unchanged after Lubuntu installation. After using lxappearance to change theme to "Industrial", the symptom disappeared. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760818 Title: gedit and gnome-calculator transparency/graphics corruption issue when GTK_IM_MODULE=xim is set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1760818/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
