Qt 4.5
I wonder what's up with QtDemo? I have this in both Linux and Win32 on my laptop. Could it be the ATI X1800 graphics card, or is it something else...
Update! Helder told me to add the -low argument and that makes it work...

I got the sam error on my Windows XP, 7 and my Gnome. Card is ATI RADEON HD3200.
I've seen various people blogging about this bug today..
You're lucky... something like that sometimes happen to me... to all the desktop, not just a single application. I've to reboot X to make it work right again :( (nvidia quadro nvs 160m with binary driver)
Try the vesa driver...
But the vesa driver is sloooow when I run TuxKart...
Hej, Johan. This is a known problem at QtSW, and it's a graphics card/driver issue. Try running the demo with the "-low" option. It will turn off some "special effects" used in the program and it should appear fine then.
My work machine is KDE 4.2, Kubuntu Jaunty. NVIDIA 6600 GT, with no problems like that.
My home machine is KDE 4.2 Kubuntu Jaunty and NVIDIA 9800 GTX+, again with no problems. Formerly this was running Vista with Qt 4.5, and also no problems.
Thanks Helder - that made it work. Isn't there a soft way to detect if the cool stuff can be run to avoid these "mishaps"... I got scared :-)
I have the same error on an ATI Radeon HD2400, Windows XP. I have a commercial license and tried to work the Qt support to troubleshoot the issue; however, they showed no interest in actually fixing it. -low flag isn't really a solution and I am very disappointed with the level of support Qt Software provides.
Obviously the ATI cards can handle the hardware acceleration, Qt must be doing something weird with ogl to cause this problem. Pretty lame and amateur if you ask me.
Have a look, that is this bug:
