Created attachment 197304 [details] Screenshot with indication of the button How to reproduce: Windows 11 Right click on the desktop Display settings Scale: 150% or 200% (not 100%) Start LibreOffice Calc Select some rows or columns Group them (F12 or Data - Group and Outline - Group) Click on the - button, not in its top left corner, to hide the group. In my case, nothing happens. Only clicking in the top left corner works. Both the - and + buttons have this issue. It seems to be that one quarter of the button is clickable and three quarters are not. When I change the scaling in Windows Display settings while LibreOffice Calc is open, it does not change the issue!!! The problem does not appear or disappear while LibreOffice is open. Only the scaling when LibreOffice started is taken into account. I tested with two monitors. Both need to be at 100% scaling. The problem is always present at both monitors together, even when only one is not at 100% scaling. I discovered the issue while I was using the laptop without an extra monitor attached. Turning hardware acceleration on or off does not make a difference. Using or not using Skia for all rendering does not make a difference. Using Skia without forcing software rendering, causes LibreOffice to crash and close.
Confirmed with STR The target area of these "group" buttons does not seem to scale. Neither do the buttons. Version: 25.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 54a836fa5af3428d893cffe5d7a0963b092e9f70 CPU threads: 8; OS: Windows 10 X86_64 (10.0 build 19045); UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL threaded
The whole widget seems off, the list of groups shows as stacked, and each collapse/expand button set don't respond well to UI scaling.
