What is your operating system? Do you use screen scaling?
And attach the file that is giving you problems
(In reply to Oliver Sander from comment #1) > What is your operating system? Do you use screen scaling? windows 10 64 bit
(In reply to Oliver Sander from comment #1) > What is your operating system? Do you use screen scaling? scaling 125%, 2 monitors
Is it blurry on both monitors? Is it blurry if you set scaling to 100%?
(In reply to Oliver Sander from comment #5) > Is it blurry on both monitors? Is it blurry if you set scaling to 100%? Ah, relevant Hhiint: It is blurred at 2 monitors but not on the thrid which is the laptop. Blurring disappears if zoom is set to 100%
This is what I expected. Per-screen-scaling hasn't seen much love until recently, because on Linux you won't get it anyway unless you use wayland. That being said, there have been a few patches recently. Can you try the 21.04 release, please, and report back?

What about the nightly builds mentioned at https://okular.kde.org/download/ ?
(In reply to Oliver Sander from comment #9) > What about the nightly builds mentioned at > > https://okular.kde.org/download/ > > ? Strange enough: i tried exactly this, same version as before. Now I tried some minutes before, now it is a newer Version. Whether it is better? Maybe... I dont know really. Still sometimes I cannot distinguish -, = and + always.
Okular uses qApp->devicePixelRatio() in some places to get the screen scaling. It should return 125%, because that is your highest scaling. Apparently it returns 1000% instead, so it is sharp only on your laptop display. If you disconnect / turn off the laptop display or set it to 125% too, is it sharp then?
> Okular uses qApp->devicePixelRatio() in some places to get the screen scaling. I thought I fixed all that, but I may be wrong. The only remaining per-screen-scaling issue I know of is https://invent.kde.org/graphics/okular/-/merge_requests/368 (which only bites if you use presentation mode).
