* Lazarus/FPC Version: <lazarus_4_0RC2-53-gd8c872d8a2 FPC 3.2.2 x86_64-linux-qt5> * Operating System: <Slackware 15.0 + Update, LiveCD, xfcd 4.16/x11> * CPU / Bitness: <x86_64, VirtualBox 7.1.6> ## What happens when open Tools->Options..., the mouse buttons became no functional, keyboard still responsed. after {ESC} key pressed, this dialog closed, but mouse buttons still no response in whole desktop wide sometimes clike right or middle may return normal, in worst case, after logout then login, it's still there. firstly I'm trying to locate font/color/directory dialog no refreshing, after try to reproduce this issue occured. kde/x11 is good, no any problem, include font/color/directory dialogs. on main devel env, returned to GTK2 widget, met sometimes a small dialog show WITHOUT refresh also, it feels like the exception handling form(that has {IGNORE} and {OK} on it), after {ESC} pressed it closed. ## What did you expect normal behavior ## Steps to reproduce livecd downloaded from us.liveslak.org, booting in vbox install fpc compiler compile lazarus run, open Options form. (give 16GB mem to vm, all this could be done in memory, no need to install who distro)
