When moving cursor over panel on the components that contains pop-up, graphic artifacts appears - see screenshot in the URL field. It's not very visible when movement is slow but faster breaks screen a lot. Even on other non-primary displays. When moving faster, pop-ups are even shown on different displays and animated. It happens on task manager, systray etc. Seems like the first release I realized this is 5.5.95. It doesn't matter what compositor method is selected - OpenGL (GLX, EGL), XRender. Reproducible: Always Steps to Reproduce: 1. select some component/widget on the panel that shows pop-up (task, systray icon etc) 2. wait for pop-up to appear 3. move quickly over other components that has pop-up (but the same type) Actual Results: Graphic artifacts, even on other displays (not only primary) Expected Results: No graphic artifacts cat /etc/fedora-release Fedora release 23 (Twenty Three) rpm -q plasma-desktop plasma-desktop-5.5.95-1.fc23.x86_64 rpm -q qt5-qtbase qt5-qtbase-5.6.0-7.fc23.x86_64 (same result on qt 5.5 though) 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) rpm -q xorg-x11-drv-intel xorg-x11-drv-intel-2.99.917-19.20151206.fc23.x86_64
I'm seeing the glitches with plasma 5.65.95 and intel graphics, too.
5.6 is really old and this implies something is wrong with the graphic driver/Qt of the time. Is this still an issue? Please reopen if so
