Scaling problem on Win10 for XNVMP - Version 0.97.0 64bits (Sep 23 2020)

Post by rdomak »

I just installed the latest XNVMP Version 0.97.0 64bits (Sep 23 2020) on my Win10 notebook with 1920x1080 resolution.
I use the screen with 150% scaling and the UI of XNView is almost unusable, longer menus are truncated, buttons on the bottom of menus aren't visible and in general the displayed content on the screen is just too large.
If I switch to 125% then everything becomes suddenly miniscule, way too small again for normal use.

I attached screenshots of both modes - nothing was changed in the layout and you can see how it's out of proportions.
The previous version on my computer was OK (I cannot recall unfortunately, which was the last one but I'm not sure that I did update lately).

I post also a screenshot with the View menu open on 150% display scaling.

That's not a perfect solution. Opening with this argument will make toolbar icons look as small as 100% scale. The image below is opening XnViewMP under 4k 15.6inch monitor using this argument.

Also, open XNV by double clicking an image cannot use this argument.

I'm using 4K display with 150% scaling. Since 0.97 XnViewMP has extremely large UI (pic 1). If I add env variable QT_AUTO_SCREEN_SCALE_FACTOR with value "0", XnViewMP looks great like with noDpiScaling (pic 2). But I think QT_AUTO_SCREEN_SCALE_FACTOR is bad solution, because other apps with Qt 5.15 (qBittorrent, Shotcut) on my PC work normal without this variable.

I see that noDpiScaling does not completely disable scaling. With this argument XnViewMP looks normal scaled like all other applications. Without noDpiScaling XnViewMP adds unnecessary extra scaling. Maybe Qt makes all work and noDpiScaling must be enabled by default.

'Zoom on HiDPI screen' should be off by default

But with "Zoom on HiDPI screen" off, the image is still blurry, unlike XnView Classic and other image viewers.
