Description

qBittorrent info and operating system(s)

• qBittorrent version: 4.3.7 x64
• Operating system(s) where the issue occurs: Windows 10 Pro 21H1 x64

What is the problem

Dragging qBittorrent window between two monitors with different scaling ruins the interface. I have two monitors - 4K (main) and 2K (secondary) in the "Extend these monitors" mode. The former has 225% scaling, the latter one - 125%. If I start QBittorrent on the main display and then drag to secondary one, the interface become messed up in terms of disappeared buttons, misplaced mouse pointer (it activates controls an inch above the actual pointer location - e.g. when pointing at 5th line in the torrent list, it lights up the first one), and it's impossible to press any interface button as well. I've switched monitors and make 2K as main and 4K as secondary, but the behavior is still the same as described above. Reinstalling and resetting the settings and clearing the data - nothing helps. Additionally if I start new torrent and popup window with torrent and path selection is open - there's no OK and Cancel buttons and it's impossible to select a path on any monitor other than the one where qBittorrent was first started.

Detailed steps to reproduce the problem

1. Start qBittorrent
2. Drag with mouse or send to secondary monitor with different scaling with Shift + Win + L/R Arrow
3. Try to select specific line or control.
4. Look at distorted interface (see above).

What is the expected behavior

qBittorrent interface is working as it is intended to. With no mouse pointer or controls misplacement/disappearance.

Extra info (if any)

In my opinion, your app doesn't apply scaling of another display and stays the same (thus misplacement ) as for original monitor it was started on (as a proof of my theory - when moving the window from 4K to 2K - the font appears as very large). I've never seen this behavior before. Other apps work as they should in terms of rescaling.

@illusive-man Can you try the windows build below, it is a test build based on 4.3.7 with more dpiaware support.

You can extract & run it in portable mode or replace both qBittorrent.exe & qBittorrent.pdb files where you currently have qBittorrent installed.

Test Build:

https://github.com/xavier2k6/qBittorrent/suites/3442116007/artifacts/81621389

[illusive-man]

Yes, this build works flawlessly! Thanks! Will we see this fix in the coming release?

FYI What's interesting is that it only works when unpacked to a new location. Replacing old files for previous installation gives nothing at all.

[xavier2k6]

Replacing old files for previous installation gives nothing at all.

Can you explain?

[sakkamade]

Replacing old files for previous installation gives nothing at all.

Can you explain?

I guess this:

replace both qBittorrent.exe & qBittorrent.pdb

?

EDIT: Oh, you mean what exacly is "gives nothing at all".

[illusive-man]

Sure. I've unpacked both .exe & .pdb files from your archive to install location for qBittorrent (replacing old files), exited the app from a tray icon and waited for couple secs for process to shutdown. Then I started qBittorrent but behavor remain the same. After unpacking to a completely new location, it works perfectly now.

[illusive-man]

Oh, sorry, my bad! :) I mean it didn't fix described behavor until I unpacked to a new location. :)

[xavier2k6]

Are you sure the files were replaced correctly as you still had qBittorrent running??

Close app completely/make sure it's not running & then replace files.

[illusive-man]

Did it again, exiting the app prior replacing (no errors while doing that). After that compared files by content - those are new files definitely. Result is NOT dpiaware.

[xavier2k6]

@illusive-man after replacing the two files where you have qBittorrent installed, what is shown in DPI Awareness column of Task Manager? (you may need to enable this column)

[illusive-man]

qBittorrent.exe : Per-Monitor

[illusive-man]

And when I start from a new location it reads: Per-Monitor (v2)

[xavier2k6]

qBittorrent.exe : Per-Monitor

are the files dated 08/08/2021??

[illusive-man]

It's August 9 2021 (09/08/2021) for me (Moscow, GMT+3)

[xavier2k6]

qBittorrent.exe : Per-Monitor

This suggests the "old files/original" to me dated 03/08/2021 & not the "New"

The "New" files should show Per-Monitor (v2) too even in the installed folder.....

[illusive-man]

[illusive-man]

left: old files replaced right: unpacked files (new location)

[Chocobo1]

@illusive-man Could you please post the file content of "qt.conf" in the left window?

[illusive-man]

[Paths]
Translations = translations

[Platforms]
;WindowsArguments = dpiawareness=1

FYI Uncommenting last line doesn't fix the issue.

[xavier2k6]

@illusive-man what happens when you double-click the .exe from within your installed location C:\Program Files\qBittorrent?

[illusive-man]

I thought I told you already. If I start the .exe from the left pane it starts qBittorrent window in non-dpiaware mode. Closing it and starting the one on the right gives me qBittorrent in dpiaware mode. Either magic or manifest. )

[xavier2k6]

I was just wondering if you were loading it from a shortcut that perhaps had other environment changes.

For me - this is what I get on my machines (when running it in portable mode & swapping out the originals)

EDIT: I exposed the Image path name column in Task Manager

[illusive-man]

Sorry for delay, I was pretty busy at the end of the week.

No, I was starting the app itself, not a shortcut. For left pane .exe it shows Per-Monitor and for the right one Per-Monitor (v2).

I don't get it myself, but it's exactly as it is.

[illusive-man]

Hi. If you're going to implement dpiaware behavior in the future release, we can close this issue. Let me know which version to await.

[xavier2k6]

@illusive-man Qt are going to be doing it by default in Qt6. there's currently a 4.4.0 qt6 rc1 version available to use for windows 10+ on the main site.

We will migrate to Qt6 in the near future but no final eta yet.

[illusive-man]

@xavier2k6 Thanks for the info. Then there's no point in keeping this issue open! ;)
