--- Comment #33 from Francisco Navarrete <paco.j.navarr...@gmail.com> --- I tried with latest neon, and again appears this issue. Tried everything. It is the compositor, because I removed it from the startup and used compton flawless. This is a major bug because a lot of tools become unusable. My latest discovery: the Android emulator. I tried: - All kwin enviroment variables suggested here. - Changin nvidia full composite and vsync - Disable all desktop effects - Tried opengl2, 3 and xrender - all options from the menu about screen painting - and a large etc I suggest to focus on this bug because turns KDE unusable for productivity in most cases. The only workaround worked is to use another compositor that actually works like compton. Kwin compositor is non usable. At least at my 4 computers, same problem on different configurations, different cards, different distros.
