Description: I am using LibreOffice already for a long time with SAL_USE_VCLPLUGIN=gtk3 flag, because the UI is too small under QT6 with fractional scaling. In the settings I use the same automatic values. Also, no matter how big the UI gets, the style selector is the same small size, which makes it impossible to use, due to scrolling problems. (The version is unspecified, because this is a very old issue) Steps to Reproduce: 1. Launch Writer (for example) under KDE 2. Choose the Tabbed UI under the User Interface settings 3. Apply to All Actual Results: The tabbed UI becomes cropped to the left, and the styles selector gets very small without detailed scrolling. Expected Results: The UI should be bigger throughout the whole tabbar, and the style scrolling should be bigger, or at least normally scrollable. Reproducible: Always User Profile Reset: Yes Additional Info: I use Wayland, the fractional scaling is set to 125% on a 1080p screen. The issue appears only with fractional scaling and QT.
Created attachment 199042 [details] QT6 125% Fractional scaling UI Here you can see, that the UI is small and Style selector is scrolling to beginning or end.
Created attachment 199043 [details] QT6 100% Fractional Scaling UI Here you can see, that the UI is fine and usable without fractional scaling, and the style selector is scrollable (yay!)
Created attachment 199044 [details] GTK3 125% fractional scaling UI As you see, the UI is fine, it works, no complaints.
Created attachment 199045 [details] QT6 150% Fractional scaling UI As you see, the issue is still present on 150% view, so theoretically, in general fractional scaling is unstable.
