I'm looking forward to seeing how much the upstream changes fixes all these. Yes, I also saw some of the other transient effects noted above; the gnome-shell text part of it was just the bit I managed to isolate and find consistency in. :-)
I had seen the need to apply scaling twice - sometimes, and titlebar text being unscaled at first, but fixing itself before long, I think after some particular thing happens that I haven't yet identified. (I think going to activities view and back fixed it, for instance, but not sure about that yet.) Some apps still having small text was "fixed" by setting the old scaling-factor setting, but I knew that wasn't a proper fix, just hoped it was an observation that might help someone narrow it down. IIRC I think one of the upstream bugs mentioned relates to that already. TBH I never did see any point in changing the text-scaling-factor setting (the font size multiplier in gnome tweak tool). It just makes the text that already is right go wrong, so I never found it to be useful. My only mention of it was to show how the problem, for me anyway, only affected gnome-shell *text*. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1713323 Title: HiDPI support partially broken after upgrade to Gnome 3.25, 3.26 Status in gnome-shell package in Ubuntu: Confirmed Bug description: After an upgrade this morning that took in the new version of this package, and a suite of gnome-session/gnome-settings packages, which may also be implicated, support for scaling on HiDPI screens seems to have partially failed. Partially. BTW I invoked the bug reporter with "ubuntu-bug ubuntu-session" but when I got to the launchpad page it had pre-filled "gnome-session". One presumes there's a reason for that so I've left it, especially as this does affect "GNOME" as well as "Ubuntu" sessions. But I do note a settings migrations utility in ubuntu-session which I wonder if it might be implicated. (TBH looking at it it's not obvious why, though it does reset scaling - that's not the problem, the problem is that it can't be set back to a combination that works.) Reminder all the stuff I'm reporting below as being wrongly-scaled was scaled correctly before the update that just took place. Enpass got a little help from having some QT env variables set, but that's it. Logging in under session "Ubuntu" (Wayland - on a different machine as this one being nvidia doesn't support it) or session "Ubuntu on Xorg" - also affects GNOME sessions: * The fonts in the top bar, and the menus and indicators accessible from there, are unscaled. The indicator icons *are* scaled correctly. * The fonts in the applications view are unscaled, but the icons and layout *are* scaled correctly. * Menu titlebar *text* is unscaled. close/minimize/maximize widgets *are* scaled correctly, as is the titlebar's size itself. * The mouse pointer is unscaled. * Non-Gnome apps, either QT or GTK (examples: enpass, nextcloud- client, hexchat, sublime text 3) are unscaled, or in some cases are a bit confused, with some elements correctly scaled, but again fonts are not. * Also on a personal note, Java 9 JavaFX apps are no longer scaled. (In Java 8 it was already broken; I was targeting Java 9 with my development partly *because* its HiDPI support was working in Linux.) FYI Java 9 JavaFX uses GTK3, Java 8 uses GTK2. ## What is working: * Gnome apps (eg: Terminal, Transmission, Settings, Tweaks, Nautilus, Gedit etc. etc.) are all fine. Although note those that use a "normal" titlebar (eg: Terminal) rather than an integrated one (eg: Nautilus) show small titlebar text as mentioned above * Google Chrome, Thunderbird, Firefox are fine (although the latter two aren't being updated for Artful yet, just sayin' ;-) ## What happens if I try to fix it: gsettings org.gnome.desktop.interface scaling-factor appears to no longer be operational. Changing its value from 0 (default), 1 and 2 appears to have no effect on anything any more. It used to be setting it to 2 fixed the few things that weren't right by having it set to 0... Correction, that *does* fix it for Java 9 JavaFX, it must be reading that setting directly. But nothing else reported as broken above is affected by changing this setting. Nor in fact does setting it to 1 cause gnome apps to be unscaled. gsettings org.gnome.desktop.interface cursor-size is working. I can set it to 48, double its normal size, to get back normal-sized cursors when the pointer is over newly-launched applications. But that's obviously a workaround. gsettings org.gnome.desktop.interface text-scaling-factor set to 2.0, also exposed in Gnome Tweaks, unsurprisingly makes text twice as large. That "fixes" it for the applications that are reported as being unscaled above, but it also doubles the size of text in gnome apps as well, so those are now far too large for the windows they're in. Google Chrome is unaffected by this, as is Java 9 JavaFX, but Thunderbird *is* affected. I noticed a new gsetting: com.ubuntu.user-interface scale-factor, but it seems to have a nonsense-value "@a{si} {}". I have no idea if this is anything in use or if it was an intended Unity 8 thing. I didn't try anything with it.
