Nvidia 驱动程序使屏幕区域变得模糊

Question

我的屏幕在未更新/更改的区域中不断模糊。看起来驱动程序一遍又一遍地对同一图像应用某种抗锯齿，导致静态区域随着每个新帧变得更加模糊。

I've had this issue for about one year now and on various distros / desktop environments, but it only occurred occasionally right after closing a game and went away after a reboot. That same thing happened again yesterday, but rebooting didn’t fix it this time. I already tried rolling back from driver 435 to 430 (which used to work), but that didn’t help either. The nouveau driver seems to work just fine though, my Windows installation doesn’t have any problems either. Here are my current specs:

• Kubuntu 19.10 w/ Linux 5.3.0-26-generic (64-bit)
• Nvidia GTX 1070ti (driver 430.50, had the same problem with 435.xx)
• KDE Plasma 5.16.5

I made a Google Drive share containing an nvidia bug report log and a video showing the blurry effect (I made sure there are no visible compression artifacts, this is what my screen actually looks like).

How can I get rid of this strange behavior? If you need any more information, just let me know. Thanks in advance!

Answer 1

我引用了相同的设置。

我遇到了这个模糊问题，并将其追溯到在 Nvidia 设置中启用 FXAA。最初我出于好奇启用了此功能，并没有发现任何区别。然后我就忘记了。昨天我应用了可用更新，突然出现了这个模糊问题。经过多次徒劳的挣扎，我回想起摆弄 Nvidia 设置并返回那里。它说得很清楚，启用 FXAA 会禁用抗锯齿，但在我的 Kubuntu 设置中，我启用了抗锯齿。出于某种原因，仅禁用 FXAA 并没有恢复预期的行为——我不得不将应用程序设置更改为增强，然后模糊消失了。然后可以返回默认的应用程序设置。
