--- Comment #4 from unhappy-end...@protonmail.com --- After more testing, the problem doesn't happen when disabling the following in winecfg: Allow the window manager to decorate the windows Allow the window manager to control the windows The previous comment containing kf.windowsystem: static void KX11Extras::forceActiveWindow(WId, long) may only be used on X11 is invalid, since I ran another installer program and that error did not pop up in my log. The issue always happens with the Plogue Chipsynth OPS7 installer. It's free so you can download it to test: https://chipsynth.s3.amazonaws.com/WIN_chipsynth_OPS7_v1.120.exe Cherry Audio Elka-X also triggers it 100% for me: https://store.cherryaudio.com/downloads/elka-x-windows-installer Both links are free to download without any hassle of using an email to sign up for a demo or having to purchase a product prior to downloading. Again, apologies for the multiple posting but I wanted to get as much information for you guys as possible. This is about all the trial and error I can do at this point. Thank you very much in advance. -- You are receiving this mail because: You are watching all bug changes.
