OK. I'm sick and tired of this crashing my computer. When running Desktop Effects, when I open certain windows, they open but showing no content, and it lags my computer a huge amount such that my mouse and keyboard become unresponsive. Sometimes if I move my mouse, 5 minutes later I see a change. Sometimes I can save my computer by doing alt-shift-f12 to turn off effects, then things go somewhat back to normal (with rendering glitches, eg black spots), but most of the time it becomes so unresponsive keyboard and mouse do nothing. Then I have to force shutdown my computer. I am using NVIDIA. Anybody else experiencing this?

Here are some windows that always cause this crash (as long as I have desktop effects enabled):
- KAlarm. I start it up, I minimize it to the systray. Now if I click the systray icon with desktop-settings enabled, it does the thing described above.
- The Konqueror settings window does the same thing. (The settings window in Kontact has been known to do the same too once in a while)
- Starting just KMail (not Kontact).

Sorry for the lack of screenshots, as once this happens I can't exactly screenshot it

Specs:
CPU: AMD Turion X2 Dual-core
GPU: NVIDIA GeForce 9100M G

The NVidia driver are know to cause some problems. Some workarounds are discribed in this userbase article: http://userbase.kde.org/GPU-Performance
But at least, the only real solution will be a working driver, and this is an NVidia issue...

I know about the NVIDIA issues and I have tried all the "fixes" on that page. None have worked. Without fail when I activate KAlarm, it will lag my X to the point of unusability.

What right I'm now more concerned about is "are these NVIDIA issues ever going to eliminated"? If so, how long would this be?

Unfortunately, the only ones who can answer that question are the NVIDIA developers. Since the driver is closed-source, no one but them can look at the code and find and fix the problem.

I know that. However are the KDE people working with them/contacted them? Surely they must understand the impact they're making on a huge open source project and the negative effects it has on their own product?

The NVIDIA devs seem to be pretty much aware of the problems and they are working on them.

By the way, what drivers are you using? The latest in Portage are nvidia-drivers-180.27 - you may want to give them a shot if you're not already using them.

Yes I am using the 180.27 drivers. Looking forward to having these issues fixed

I'm marking this thread as solved because there isn't really much that can be done at the time except to wait for the NVIDIA guys to do their stuff.
