As I said in the other bug (1202446), can you attach a screenshot of this working please?

See the screeshot. I just did:

mkvtoolnix-gui -style adwaita-dark

... and the dark them is applied to the QT6 version of the app (look at the system info in the dialog: QT6 6.3.1). (I am on Gnome).

I'm gonna work on this this week.

This is awesome. Many thanks. -- You are receiving this mail because: You are on the CC list for the bug.

Nice, it works fine on gnome 43, but now I moved to KDE due to poor 4k hidpi support in gnome and there is a new PROBLEM: Tested with mkvtoolnix-gui: 1. with KDE scaling at 150% I have to start mkvtoolnix-gui with "QT_SCALE_FACTOR=0.7" otherwise everything is too big. 2. all the icons in the app mkvtoolnix-gui are missing in KDE (it is fine on gnome). Is this something you can also look into, or should I open a new report with KDE for qt6 apps ? Thanks. -- You are receiving this mail because: You are on the CC list for the bug.

...

It's nice to here it's working for you.

This was on KDE. On Gnome it still isn't applying the theme.

So, you fixed the qt6 apps (great thanks !), but the qt5 apps sill never had the adwaita theme applied (on gnome qt5 apps have a greyish-greeny theme).

What about that ?

I'm sorry to hear that, but I have to say I was under the impression, according with you report on https://bugzilla.opensuse.org/show_bug.cgi?id=1202446, that other Qt apps were fine.

(and on X11 Gnome hidpi (4k) the qt6 and qt5 scaling is completely different. Is there anything you can do about this ?

I'm not sure right now.

By default qt6 scaling was fine, but qt5 was too big (when using 150% font scaling in Gnome).

I was able to fix the qt5 scaling by adding these to /etc/environment

...

export QT_AUTO_SCREEN_SCALE_FACTOR=0 export QT_SCREEN_SCALE_FACTORS=1.5 export QT_SCALE_FACTOR=1

But now the qt6 mkvtoolnix has the same problem qt5 apps had before.

So, either qt5 scaling works or qt6, but not both together.

Ayn idea how to fix this ?

Thanks.

Since bugzilla is no place for user support we can use other channels instead, be it using mailing lists be it instant messaging in IRC/Matrix/Discord. There are many people out there in the openSUSE community that may have more accurate answers and maybe know if there's something to be done on our side to help the problem go away or at least mitigate it. Now, when the changes I made to QGnomePlatform arrive at Tumbleweed we can have another look how Qt 5 and 6 apps will behave for you. Maybe this scaling issue could be some kind of limitation Adwaita-qt has or whatever, for now I can't say much. I don't want to start chasing bugs just yet. Then if the issue(s) still persist(s) (Adwaita not applying for Qt 5 apps and/or the scaling mess), even with the new changes of QGnomePlatform, you can open a new bug targeting that/those issue(s) and please CC me, OK?! -- You are receiving this mail because: You are on the CC list for the bug.

QT5 apps have always been using the QT5 dark theme instead of adwaita (but this was ok for me as they switched to a dark theme). But yes, as you fixed it I think using the same theme across the board is the better way.

Now, when the changes I made to QGnomePlatform arrive at Tumbleweed we can have another look how Qt 5 and 6 apps will behave for you.

It has finally landed with snapshot 20220929. Thanks ! 2 issues: 1. qt5 apps still don't use the gnome dark color theme (they use greenish-grey, gnome is brown (on a properly calibrated screen, when not calibrated it can look grey)). 2. Qt6 apps now use the gnome theme colors (on mkvtoolnix (qt6) it isn't perfect as it seems to use only one color tone, but on Fedora 5 month ago the qt5 version was using the different colors tones to draw the different window sections correctly in different tones).

http://bugzilla.opensuse.org/show_bug.cgi?id=1202526 http://bugzilla.opensuse.org/show_bug.cgi?id=1202526#c17 --- Comment #17 from Luciano Santos --- Of course it's still not working for new installs, and that's because the changes I did still haven't landed on Tumbleweed. I made some rather drastic changes in the package so we let it stay for a while in the Gnome devel projects for some testing. Then before it landed on Factory (where it will then get tested by openQA and if all goes well it lands on Tumbleweed) there were new releases for both Adwaita-qt and QGnomePlatform. All of this made the process take a little longer. But this Friday's TW snapshot 20220929 we got Adwaita-qt 1.4.2 [1] so on this weekend we probably should get QGnomePlatform 0.9.0 which includes the changes I did (QGnomePlatform-qt6) and a bot will add a comment in this bug referencing the update.

FYI this status seems wrong, because I just checked again, and with snapshot 20220929 I also got QGnomePlatform 0.9.0 (and it is installed from the TW OSS repo).

Are you sure it's coming from OSS? I highly doubt that since QGnomePlatform 0.9.0 depends on Adwaita-qt 1.4.2. (In reply to C J from comment #20)

Created attachment 861904 [details] GOG games installer dark theme bug on Gnome

Added 2 new screenshots with another QT dark theme bug on Gnome:

1. hplip settings (can't read the text and button labels) 2. GOG games installer (same problem)

(this is QT but not QT6, is this also something you can handle here or do you prefer me to open another bug report?)

Thanks.

No, no. This bug is called "QT6 apps don't get Adwaita styling applied under GNOME" and that's exactly what we are trying to fix here. Nothing more, nothing less.

You can disregard my comment stating we'd se a bot commenting here when the updates would land on Tumbleweed repositories, they seem to happen only for maintenance updates for openSUSE/SUSE stable releases. I'm closing this bug since our job here is done, both Adwaita-qt 1.4.2 and QGnomePlatform 0.9.0 are already one Tumbleweed (and it looks like QGnomePlatform didn't get an entry in the Tumbleweed snapshot changes log, which is weird for me BTW) and they carry out the fixes for this bug. Since you are still seeing problems with Qt 5 apps, again, I suggest filing a new bug for this specific issue. -- You are receiving this mail because: You are on the CC list for the bug.

The mkvtoolnix 71.1 dark theme is now back to missing the darker color tone again (The app sections are now all brown in a single color tone).

I don't know which package is causing this?

Perhaps these 2 problems are linked/have the same cause as they both happened with snapshot 20221016 or 20221015: Bug 1204434 ("export QT_SCALE_FACTOR_ROUNDING_POLICY=PassThrough" in /etc/environment doesn't have any effect anymore, but passing this variable when starting an app in gnome-terminal works). -- You are receiving this mail because: You are on the CC list for the bug.

Can you attach a screenshot of how the app looks like when this issue comes back?

Done, see above.

Is it only mkvtoolnix or other QT6 apps present the same behavior?

I think mkvtoolnix is the only qt6 app I am using, so I don't know. Thanks. -- You are receiving this mail because: You are on the CC list for the bug.

It seems unlikely that was 20221114 [1], it only brought three package updates:

Ah yes, that's why I first thought that it was 20221115-0 as I updated on 11.16, but today it updated from 20221114-0 to 20221115-0. So the culprit is probably 20221112 or 20221113. -- You are receiving this mail because: You are on the CC list for the bug.
