Sorry for the vagueness of the question, but I am experiencing slow and jerky vertical scolling in Calc after upgrading to a “modern” CPU (Ryzen 6600H/16G memory) and a 4K screen. I was looking forward to viewing large Calc sheets with this display.
Vertical scrolling performance is much slower that it was on my former HD display running Fedora Linux with a basic Core i3. In other words, when I scroll down the sheet with the mouse wheel, it takes the sheet one or sometime even two seconds to catch up. It’s slow regardless of how much of the sheet I have exposed, i.e. whether the window takes up only 1/4 of the screen or whether it’s fully maximized.
This doesn’t happen with other apps like web browsers and wordpad. Performance is excellent on Chrome for example.
Is this a known issue? Any tips? I know this is probably some evil interaction between some random layers of the app or my Windows settings. I suspect Cleartype somewhat. I have been fiddling around trying to make the display look good and maybe some settings I’ve made are freaking out Calc:
- Overall windows scaling: 125% (this setting has no effect as far as I can tell.)
- OpenCL on/off has no effect
- Choice of font seems to have no effect, but Cleartype sometimes makes fonts look bad until I have exited and restarted Calc. Arial seems less affected by this. Turning off Cleartype at this resolution makes everything look terrible and doesn’t seem to have much effect if any.
- Ther aren’t any Cleartype parameters to share, but in summary I’ve struck a balance between blurriness and the “too thin” look.
- The file is on a file server. I switched from NFS to SMB when I made the upgrade, but there doesn’t seem to be any network activity once I have the Calc document loaded so doubt this has an effect.
Has anyone looked into this?
