Fault to render on secondary Hdpi (4K) monitor

[Franco-64]

Hi, after a fresh installation and a change of some line in [video] section of config.ini, Stellarium opens correctly in the secondary 4K display, at full screen. But the planetary image occupies only a section of the screen (see image). It seems also that the selection of sky objects in misaligned with what I see in monitor (I can click and have some results in the black area), as the app sees "internally" as the visualization was in full screen. No change after i pressed F11 twice.

This is my video section of config.ini:

[video]
dithering_mode = color888
fullscreen = false
maximum_fps = 10000
minimum_fps = 18
screen_h = 2160
screen_number = 1
screen_w = 3840
screen_x = 0
screen_y = 0
tm_display_adaptation_luminance = 50
viewport_effect = none

Expected Behaviour

Rendering full screen

Actual Behaviour

Steps to reproduce

After a fresh installation of latest stable version (stellarium-23.4-qt5-win64.exe)

• Stellarium version: stellarium-23.4-qt5-win64.exe
• Operating system: Windows 11 Version 22H2

Does this still happen if you disable HiDPI scaling?

[Franco-64]

It depends. I use 200% scaling on 4K monitor for best viewing of menu and windows, and the behavior is uncorrect as described. If I use 150% or less, is OK. With a scale of 175% or more, the issue reappers.

Issue is present in both case: if I launch the app after rescaling, and if I rescale when Stellarium is open.

Note: only at "recommended choice" (150%) it is possible to point, click and obtain correct result of recognition of sky obiects. At other resolutions (also the less enlarged, 100% and 125%, with full screen rendering) object recognition is misaligned.

Hope to help...

Does this happen in previous versions of Stellarium, like 23.2 and 23.3?
