I have recently installed Fedora 21 x86_64 and when KDE starts the mouse pointer appears to be constantly redrawn producing an effect like the old(?) Windows setting for mouse pointers called "tails". This makes KDE VERY difficult to use. Reproducible: Always Steps to Reproduce: 1.Unknown 2. 3. Actual Results: see above Expected Results: see above KDE is usable but this problem makes it VERY HARD TO USE. I'm not sure "grave" is the right severity level though.
Please report X display issues to https://bugs.freedesktop.org/ Depending on the used video driver, it might also make sense to additionally report to its developers.
Christoph, Can you give me some more info please? How did you make the determination that it was the X server? KDE has mouse pointer config options. How do I tell which driver is being used by my system? Regards, George...
The mouse (pointer) is controlled by the X server, not the KDE applications. Check /var/log/Xorg.0.log to see which video drivers are loaded. But the X developers there know better which information is relevant.
Christoph, I will do as you suggest. Thanks for your help, George...
Rex, I reported this problem to bugs.kde.org who asked me to file a bug with the xorg developers. I don't know what to do about this bug. Do you guys modify the X server or drivers? I can post any solutions I find here if that would be something you would like. Regards, George...
It's most likely a video driver issue, depending on your video chipset, may make sense to file against the appropriate one in the distro too @ http:/bugzilla.redhat.com
Rex, lspci | grep vga says this: 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 550M] (rev a1) Is anyone working this bug? Thanks, George...
George, certainly not here. Depending on whether you use nvidia binary drivers or nouveau drivers, you need to ask their developers. See comment #1 and comment #3.
Hi, As far as I'm concerned this bug can be closed. I'm on Fedora 27 (rawhide) now and havve not seen the bug in years. Thanks for your help, George...
