Two (possibly related) problems. I'm unable to determine actually which state the screen font anti-aliasing is in due to it, as well. First off, screen font antialiasing causes performance problems. In calc, it takes multiple seconds after I enter anything in a cell before it displays. This seems to be corrected when I toggle screen font antialiasing in Tools->Options->Libreoffice->View When I restart the program, the actual state appears to be reset, but the checkbox itself is not (it remains in whatever state I last had it). So I cannot even tell if antialiasing is enabled or disabled to get the performance problems. This problem occurs whether or not I toggle hardware acceleration, opengl, or "use antialiasing" on the right side of this menu. In face, I'm not sure what the practical difference between "screen font antialiasing" and "use antialiasing", as the tooltip simply says "restart required" for the latter, and the former has no tooltip. Is the latter for the interface? The former seems reasonably self-explanatory, though.
Do you get the same performance hit with an AppImage daily build? http://libreoffice.soluzioniopen.com/

I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' once the question has been answered
Sorry for the delay. These issues seem to be mostly resolved in 6.0.1.1. I noticed some other oddness with 6.0.1.1, such as the HW Accel checkbox being disabled when the use OpenGL checkbox was active. This might be intentional, I could be wrong. Is "Use OpenGL for Rendering" really "Use software opengl for rendering" vs "use hardware opengl for rendering"? If this is not the case, then I will probably check the daily and see if this is present there. Has anyone been able to explain what the difference between "Antialiasing" and "Screen Font Antialiasing"? Is one *everything* vs the other *just fonts*? I'll let you set the status on this one, according to whatever you think makes sense. I'm setting it as unconfirmed/fixed.

"Use OpenGL for Rendering" will use your graphics card for rendering the user interface. There are a lot of problems on Linux with it. > Has anyone been able to explain what the difference between "Antialiasing" > and "Screen Font Antialiasing"?
