https://bugs.kde.org/show_bug.cgi?id=414866 Nate Graham changed: What|Removed |Added Resolution|--- |INTENTIONAL Status|CONFIRMED |RESOLVED --- Comment #11 from Nate Graham --- Unfortunately there's no practical way to fix it on X11 due to baked-in assumptions in X11 itself. It already works on Wayland, so there is little chance it will ever get fixed on X11, which means the overall effort will never get unblocked, which means it can't be done. Unfortunately I think we have to close this. Folks who want a decent hidpi experience will have to use Wayland and look forward to upcoming changes to improve the experience for XWayland apps in particular. Sorry everyone. :( -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414866 crupest changed: What|Removed |Added CC||crup...@outlook.com --- Comment #7 from crupest --- These are two different problems: 1. KDE Plasma should support multi-screen with different xrandr scale. As far as I've searched, this is the "best" way to deal with multi-screen with different DPI. By far, the function is buggy as you can see in bugs searched with "xrandr scale" keywords.(https://bugs.kde.org/buglist.cgi?quicksearch=xrandr%20scale Too many so I don't list). 2. KScreen should support configuring different scale in different screen. By far, it only supports unified scale in all screens. Although KScreen is just config front-end (I think) and actual implementation could vary, it is very important to those who use multiple screens with different DPI. -- You are receiving this mail because: You are watching all bug changes.

We'll investigate whether or not per-screen scale factors is an outcome that can actually work given the technical limitations of X11.

https://bugs.kde.org/show_bug.cgi?id=414866 --- Comment #4 from Nate Graham --- I read this bug report as not asking for xrandr scaling specifically, but as using that as a workaround for the lack of per-screen scaling support in KScreen on X11. Can we re-open this to track doing it using QT_SCREEN_SCALE_FACTORS? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414866 David Edmundson changed: What|Removed |Added Status|CONFIRMED |RESOLVED CC||k...@davidedmundson.co.uk Resolution|--- |NOT A BUG --- Comment #3 from David Edmundson --- That patch has nothing with xrandr scaling. You want to find Dan's patch. The xrandr scaling method has been seen, and has been deemed problematic. Until recently there was an issue with pointer constraints without a downstream patch only Ubuntu had. There's also a massive issue that if you open a legacy app on your 1x monitor, it's quarter of the size which is a worst state than before. Obviously we don't try and break the setup you have that works (you can disable kscreen so it doesn't meddle with your scripts) - and you can set the DPI and Qt scale factor to your highest screen. But I don't want us support that, as it's an invasive change to spend time on when wayland fixes it properly. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=414866 --- Comment #2 from Marc Streckfuß --- After reading through the patch, I think deferring the scaling to X11 could even remove all the downsides of the previous patch (it would work on all applications), but might introduce it's own set of problems: With my suggestion, all screens run at the same dpi and thus have their virtual space, this means panning and scales and fonts etc is all according to the highest DPI. For overlapping windows, there are no corner-cases, they just use the high DPI, as essentially all windows have the same DPI. X11 will then take the contents and scale the pixels down, this means the windows have the same size on all screens. Downside I see is: The applications all render at a higher resolution than needed, thus have an additional load. Then the scaling process might be lossy, so it looks worse than without a multi monitor setup. As such, images might get upscaled to the high resolution and X11 scales them down again. I have the feeling that my lower dpi monitor does look worse than it used before, but I guess we can't take that as true, as I never had a comparison and now that I got a better display, I can directly compare them and see how "bad" it really was. -- You are receiving this mail because: You are watching all bug changes.
