RubyMine Mixed DPI Scaling Issue on Wayland/KDE

## Environment
- OS: Arch Linux
- DE: KDE Plasma
- Display Server: Wayland
- RubyMine Version: 2024.3
 

## Display Setup
- Primary Monitor: 2K resolution with 200% scaling
- Secondary Monitor: 1080p resolution with 100% scaling

## Issue Description
RubyMine doesn't handle mixed DPI scaling correctly when moving between monitors. When the window is on the 2K monitor (200% scaling), everything looks normal. However, when moved to the 1080p monitor (100% scaling), the content becomes too small.

## Additional Information
- Other JetBrains IDEs (GoLand, PyCharm) work correctly with the same setup
- The issue only occurs with RubyMine

## What I've Tried
- Setting GDK_SCALE=2 (affects both monitors, not desired)

## Expected Behavior
RubyMine should handle mixed DPI scaling correctly like other JetBrains IDEs (GoLand, PyCharm).
