With the arrival of the NVIDIA 450 drivers, and specially with 455 (when it all started working properly), I’ve been finally able to use my laptop (Intel HD 630 and GTX 1050Ti, and running on 5.8 kernel) in hybrid mode with my external monitor. That said, I kept having issues with my system while using it. When just having the desktop on screen everything felt smooth as butter, but as soon as I had any programs on screen it always felt like my 60Hz monitor was capped at half the refresh rate. Everything felt laggy on the external monitor, while on the laptop one it all felt smooth. After looking for what could be the issue, I found out that changing the compositor from OpenGL (both versions have this issue) to XRender solved it, but with that I basically lost some of my desktop decorations (specially blur effects). Even kwin-lowlatency didn’t manage to help with it.
For the more experienced folks, is there any way to go back to OpenGL compositing and still have a smooth desktop experience with my setup or do I just keep Xrender and I was even dumb to try using OpenGL with hybrid mode?
