[Bug 1902436] Re: Mouse slow in Xorg fractional scaling
> fractional scaling does not render the desktop at a higher resolution than your screen Xorg fractional scaling DOES render the desktop internally at higher resolution than the monitor, and then downscales it to the physical monitor. That's how you get a "fraction". For example: Monitor = 3840x2160 Scale = 150% Render resolution = 5120x2880 Transform matrix scale factor = 1.333 Final visible resolution = 5120x2800 / 1.333 = 3840x2160 You can confirm this by looking at the details in 'xrandr --verbose'. > If one could simply choose different integer scaling for different monitors that would solve 90% of people's problems. Yes you can already but only in Wayland sessions. Xorg sessions are limited by Xorg itself not treating each monitor as a separate framebuffer. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1902436 Title: Mouse slow in Xorg fractional scaling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1902436/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1902436] Re: Mouse slow in Xorg fractional scaling
Daniel, no, fractional scaling does not render the desktop at a higher resolution than your screen. Unless you are talking about xorg "Screen"s. Fractional scaling renders in a _lower_ resolution. And a bug is never expected - hence why it's called a bug. I don't even know why you would categorize it as expected. Saying something about resolution doesn't clear up why mouse tracking all of a sudden incorporates latency. I'm not even sure many people like fractional scaling. If one could simply choose different integer scaling for different monitors that would solve 90% of people's problems. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1902436 Title: Mouse slow in Xorg fractional scaling To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1902436/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
