Hello! I've installed Fedora 20 Mate i386 on an old system with GeForce4 Ti 4200 AGP (NV25) and I see significant visual defects. Many icons are not shown. They can reappear if they are selected of the mouse goes over them. Screenshot: http://red-bean.com/proski/nv25/screenshot.png All entries on the left should have icons, but only two have them. The problem goes away I create a file /etc/modprobe.d/nouveau.conf containing "options nouveau noaccel=1", rebuild initrd and reboot. I compiled Linux kernel 3.16 and I see exactly the same problem. .config: http://red-bean.com/proski/nv25/kernel.config I tried opening many tabs with flash based videos in Firefox and got a hang. At first, the mouse worked, I was able to switch to the console with Ctrl-Alt-F2, but when I switched back to X, the system was totally unresponsive and I had to power cycle it. The kernel log for 3.16: http://red-bean.com/proski/nv25/dmesg The output of "lspci -nnvvvxxx": http://red-bean.com/proski/nv25/lspci-nnvvvxxx Fedora 20 is fully up-to-date. MATE appears to be most affected, but I've also seen incorrectly drawn checkboxes in LDXE on that system. I'm ready to donate that video card to the project if anyone is interested. -- Regards, Pavel Roskin

As of yet, it has not been tracked down. I recently grabbed a NV18 card, but haven't had time to try to reproduce the issue. This has something to do with transparency use, I think. -ilia> > The problem goes away I create a file /etc/modprobe.d/nouveau.conf > containing > "options nouveau noaccel=1", rebuild initrd and reboot. > > I compiled Linux kernel 3.16 and I see exactly the same problem. .config: > http://red-bean.com/proski/nv25/kernel.config > > I tried opening many tabs with flash based videos in Firefox and got a hang. > At first, the mouse worked, I was able to switch to the console with > Ctrl-Alt-F2, but when I switched back to X, the system was totally > unresponsive and I had to power cycle it.

This has something to do with transparency use, I think.I agree, transparency may be an issue. Or perhaps the use of transparency to implement mouse-over events and non-rectangular shape. The MATE file manager icons and Gtk+ checkboxes react to the mouse-over and they have visual problems. The LXDE filemanager icons don't react to the mouse and they look fine. The icons and the checkboxes are non-rectangular. The checkboxes have rounded corners. I haven't seen visual problems with other Gtk+ widgets. -- Regards, Pavel Roskin> -ilia > >> >> The problem goes away I create a file /etc/modprobe.d/nouveau.conf >> containing >> "options nouveau noaccel=1", rebuild initrd and reboot. >> >> I compiled Linux kernel 3.16 and I see exactly the same problem. .config: >> http://red-bean.com/proski/nv25/kernel.config >> >> I tried opening many tabs with flash based videos in Firefox and got a hang. >> At first, the mouse worked, I was able to switch to the console with >> Ctrl-Alt-F2, but when I switched back to X, the system was totally >> unresponsive and I had to power cycle it.
