Blurry write and icons #6935

Closed Timmy93 closed 6 years ago

Timmy93 commented 7 years ago

System: QBittorrent 3.3.13 - Linux Mint 18.1 - 64bit

If on linux, libtorrent and Qt version:

Libtorrent 1.0.11.0 - Qt: 5.5.1

What is the problem:

I cannot see properly the window of qbittorrent because all the images and section are super zoomed, I can imagine that's a problem related to the HiDPI infact I've an old 1920x1080 Samsung screen. Until yesterday, before the update, I had no resolution problem.

What is the expected behavior:

I expect to see the write, the images and the icon not blurry as if everything is extra zoomed

Steps to reproduce:

1) Get a 1080x1920 display 2)Open QBittorrent 3.3.13

Chocobo1 commented 7 years ago

Try setting environment variable QT_AUTO_SCREEN_SCALE_FACTOR=0 and then run qBittorrent.

Timmy93 commented 7 years ago

@Chocobo1 Can you please explain me where to find this parameter to change? Is it in an external file or in the qbittorrent settings?

Chocobo1 commented 7 years ago

open a terminal/console, and type:

export QT_AUTO_SCREEN_SCALE_FACTOR=0
qbittorrent
Timmy93 commented 7 years ago

@Chocobo1 No changes also setting this variable. Here is a pic of the problem: a

yate commented 7 years ago

QT_AUTO_SCREEN_SCALE_FACTOR=0 worked for me, but is this the solution or just a temporary workaround?

GildedHonour commented 7 years ago

for me it didn't work

zeule commented 7 years ago

Blurred icons will disappear when we switch from PNG to SVG.

Timmy93 commented 7 years ago

In my case the UI too large present this problem only on the second monitor (1920x1080) while in my first one (1366x768) there are no problems. NB. I use only one monitor per time.

dgutov commented 7 years ago

QT_AUTO_SCREEN_SCALE_FACTOR=0 worked here as well.

Without it, not only the buttons were too large, but the context menus as well (the items like 3x as tall as the text inside them).

Timmy93 commented 7 years ago

Still not working any of this methods. The problem exists only when i use my second screen (1920x1080), while in my laptop screen (1366x768) I've absolutely no problem.

Tahvok commented 7 years ago

Same problem here. See screenshot as example: screenshot_20170715_163331

QT_AUTO_SCREEN_SCALE_FACTOR=0 worked. It's the only qt applications that is behaving like this.

nighto commented 7 years ago

This happens on Windows as well, although slightly different. Windows is set to 1920x1080 with 150% zoom, other apps react properly (like Chrome in background) and qBittorrent is blurry zoomed, including text.

On Windows 10 graphical settings, "Set scale and layout" is set to 150% (sorry for the portuguese screenshot):

Linux users: most likely you screen setup is misconfigured, in particular DPI is incorrect. Those, who need help with this and are running X session, please post outputs from:

  3. $ env | grep Xft.dpi

zeule commented 7 years ago

@dgutov: which one of your screens (internal with 279 DPI or external with 94 DPI) do you want to sacrifice? You joined them into a single virtual screen, but due to the too different resolutions, one of them will show font rendering problems. You can try to launch qBittorrent as follows: $ Xft.dpi=279 qbittorrent on your internal screen to see whether it makes fonts correct.

dgutov commented 7 years ago

The secondary one (it has lower resolution). Which is the usual choice for most applications, AFAICT.

You can try to launch qBittorrent as follows: $ Xft.dpi=279 qbittorrent on your internal screen to see whether it makes fonts correct.

No change. To be clear, the internal screen is the 4K one.

dgutov commented 7 years ago

By the way, qBittorent doesn't look too hot on the secondary screen either. Both buttons and fonts are too small for it.

zeule commented 7 years ago

It does not react on any value of Xft.dpi?

dgutov commented 7 years ago

Indeed, it doesn't. Certainly not how it reacts to QT_AUTO_SCREEN_SCALE_FACTOR=0.

zeule commented 7 years ago

Does it react on:

$ XFT_SETTINGS="
Xft.dpi:        279
"
$ export XFT_SETTINGS
$ qbittorrent

?

dgutov commented 7 years ago

No reaction either.

zeule commented 7 years ago 
$ echo "Xft.dpi:279" | xrdb -merge
$ qbittorrent
dgutov commented 7 years ago

That elicited a reaction. But that makes the fonts too big. The value of 192 makes them good size, but without QT_AUTO_SCREEN_SCALE_FACTOR=0, the images are still weirdly positioned on the buttons and the scroll bar controls are still pixelated.

Also note that with QT_AUTO_SCREEN_SCALE_FACTOR=0 the line spacings, buttons and scroll bars are smaller, but the text size is still affected by whatever value of DPI I've set using xrdb -merge.

IOW, there are other settings in play as well.

Timmy93 commented 7 years ago

I tried also to follow your suggestion, but it modify only the font size, the images are still too zoomed and big. immagine

zeule commented 7 years ago

IOW, there are other settings in play as well.

Obviously. What DE do you run? Do you mind showing complete output of env (with your private data removed, if you want)?

edit: I've noticed that plasma 5 comes with QT_AUTO_SCREEN_SCALE_FACTOR=0 so it's not a good example? Unsetting this variable made the same DPI issue appear on plasma as well.

dgutov commented 7 years ago

I'd like to report that after upgrading to Ubuntu 17.04, the icon positioning became much better. Some icons are stretched too much (i.e. don't have high enough resolution), like the ones on the status bar (connection status and others), but overall the scaled UI is quite usable.

zeule commented 7 years ago

@Tahvok: the difference is the presence of QT_AUTO_SCREEN_SCALE_FACTOR=0 in Plasma session, I guess.

Tahvok commented 7 years ago

@evsh indeed it is, as I've said in an edit above.

GildedHonour commented 7 years ago

when will this be fixed/

Timmy93 commented 7 years ago

I temporarily moved to transmission (or deluge) both are working fine, are open-source as well and have no graphics problem. Still waiting for a fix or a efficient and working workaround.

yate commented 7 years ago

I added export QT_AUTO_SCREEN_SCALE_FACTOR=0 to /etc/profile for my workaround. As a plus it also fixed KeepassXC and Calibre, which both have/had the same issue. I also added a pull request to do the same in the code, we'll see what the consensus is around that change.

mrturcot commented 6 years ago

I'm having this exact issue on Linux Mint 19. Only solution for me was the one provided by @Chocobo1 at the top. Issue persists on 4.1.1 & 4.2.0.

Edit - After downgrading to 4.1.1 (as no menu icon for 4.2.0). I added a line in /etc/environment with QT_AUTO_SCREEN_SCALE_FACTOR=0 Logged out of the session, logged back in, launched qbittorrent from the menu and scaling was fixed.

fabgam commented 6 years ago

Xubuntu 18.04 LTS, qBitorrent 4.1.2

Same issue reported above, fix adding this line QT_AUTO_SCREEN_SCALE_FACTOR=0 in /etc/environment. Followed by an insertion of the correct DPI value of my screen.

Chocobo1 commented 6 years ago

I've submitted PR #9444 to fix this.

Chocobo1 commented 6 years ago

Will be fixed in next release (v4.1.3).
