Default Resolution scaling issues

Hi,
I have been having this issue with jDownloader for over 4 years using Linux. Setting the font sizes makes it look worse. Regardless what distro or Desktop environment I use.

@ 1920 x 1080 jDownloader look ok
@ 3840 x 2160 jDownloader is tiny

I have over 30 apps installed, all respect, whatever resolution I set.

No issues with Mac or windows.



@ 1920 x 1080 JDownloader look ok
@ 3840 x 2160 JDownload is tiny

Pika Back up @ 1920x 1080 scale set to 100

@Blu24: Answer is easy,JDownloader doesn't yet support HighDPI. On Windows, there is windows internal feature to auto scale the UI, guess the same for Mac.
The current in use default theme doesn't support HighDPI but we're working on adding FlatLAF support which brings HighDPI support and then, once theme is properly supported, we can do the rest of work to bring fully HighDPI support.
What exactly do you mean by *scale set to* ? A desktop setting or what?

Also can you please provide screenshot of pika 200 scale, as at the moment it's same image as 100 scale

@ 3840 x 2160 the overall text is a touch too small. Scale works like zoom. The default scale is 100

@Blu24: what desktop is that? wayland? if so, then Java/JDownloader only supports X11 right now and running via xwayland then. Also unsure if xwayland/java does support that window scaling of the desktop manager at all, so I need to know which one you are using
