Incorrect scaling breaks Zoom desktop client on (K)Ubuntu 25.10

[ras_andreas]

Hi!

I'm trying to use Zoom Desktop on my laptop that is running Ubuntu Linux 25.10 with KDE installed :

I installed the RPM (but also tried Flatpack and Snap) and am having some troubles with the scaling of the application. I have a 2k display and the display scaling is set to 125% and it works on all applications (QT and GTK) except for Zoom: The font is very small on the one hand side and on the other hand side I cannot schedule meetings as the window that opens when scheduling a new meeting does not fit into displayed pane and I cannot scroll in it (and reach the "Save" button to save the meeting) - see the screenshot https://snipboard.io/V0aqZK.jpg
