SUMMARY Mono application don't scale anymore in 4k with fractional scaling (it worked fine up to a few months earlier, so something broke it). STEPS TO REPRODUCE 1. enable 150% scaling on 4k in display settings. 2. Start an app with mono ( i.ex run the gmkvextractgui exe with mono, available here: https://sourceforge.net/projects/gmkvextractgui/files/v2.7.0/ , or subtittleedit available here: https://github.com/SubtitleEdit/subtitleedit/releases , also in the AUR: https://aur.archlinux.org/packages/subtitleedit) OBSERVED RESULT You will see that the apps don't scale in 4k. (it worked a few months ago) EXPECTED RESULT The mono apps should scale in 4k. (as they did before) SOFTWARE/OS VERSIONS Linux/KDE Plasma: kernel 6.12 KDE Plasma Version: plasma 6.2.4 KDE Frameworks Version: 6.9.0 Qt Version: 6.8.1
Isn't this the same as bug 497984?
(In reply to Zamundaaa from comment #1) > Isn't this the same as bug 497984? No, they are 2 different problems, this is why I filed 2 different bugs. This bug is about mono apps not scaling at all (with the system scaling or the individual per app scaling in the system display settings, it is the same -> does not scale at all). Just run the 2 apps I have linked to with mono, and see for yourself. As I said: it worked a few months ago, so something broke it. Thanks.
Please report to Mono.
