 Posted: Fri Sep 13, 2024 1:49 pm Post subject: plasma 6 slow |
 |
|
I'm using the new "upgraded" plasma 6, but find that it is slow. That is, when you drag a window around, it leaves trails of partially redrawn windows, as the redraws can't keep up. I have very fast hardware (5950x + nvidia 1030 gpu) and this shouldn't be happening. It wasn't the case with KDE 5.
To be clear I'm using X still, not wayland. One thing at a time.
Did plasma decide to stop using hardware acceleration? This is just ordinary windows, nothing 3D.
Do I have some misconfig that turns it off? Where do I check that?
Cheers,
Jon |

I'm having the opposite problem. Wayland is what it came up with after upgrading, it was slow and when click on items there was a glitchiness. I spent way to much time trying to get gnucash fonts back to normal, way too large. Couldn't find anyway to get them to change. So finally today after all the upgrading was done. Went back to Plasma(X11) and system isn't doing any of that stuff and gnucash fonts are back to what I want. System isn't doing the glitch's either. I'm sticking with X11 for the foreseeable future. Even clicking on stuff in wayland is causing harddrive activity before it does it that isn't happening in X11.
Have you checked your nvidia settings to see if something didn't change? Did you update all the configs with etc-update,..

Similar hardware (except an old AMD gpu) and I can drag e.g. this firefox window around as fast as my mouse will move, no trails. I'd guess you've lost some hardware support somewhere.
Some bits from my KDE Info centre:

He says he is still using X though. I switched back to X cause wayland wasn't cutting it for me.
jesnow have you looked at the Gentoo wiki page for Nvidia?
Under X my NVIDIA GeForce RTX 2070 SUPER shows this:
| Code: | # glxgears
117495 frames in 5.0 seconds = 23498.969 FPS
120276 frames in 5.0 seconds = 24055.121 FPS
120106 frames in 5.0 seconds = 24021.191 FPS
120335 frames in 5.0 seconds = 24066.830 FPS
# glxinfo | grep direct
direct rendering: Yes

Here it is: Seems to all be working. Just slower than it seemed before. When I sweep a window across the screen (50cm) in one second I would expect the distance between redraws to be less than a cm at 60 frames/second. Instead it's more like 3cm. But maybe what I need is a screen with a higher frame rate if I don't want to see those artefacts.
How do you get those ultra high frame rates shown above ? Do you have a special monitor?
Cheers,
Jon.

You've answered your own question: Running synchronized to the vertical refresh. You have "Tearfree" or "Vsync" set somewhere, or it's on by default. |
