I don't recall if this started in MC32 or not, but here's the issue:
when opening a new window (save confirmation, DSP save name, etc), the new window is only a title bar the size of a single character. See attached image showing new "window" for SAVE DSP Preset (red arrow). Carefully moving the cursor to one of the corners allows stretching to see contents (assuming you can find the miniscule title bar in the first place). Since I'm running on a 4K display (3840x2160) via HDMI, I have modified several magnification factors.
Here are the configuration details that seem relevant:
system
Ubuntu 24.04.1 LTS
Intel i3-8100 x4 (built in graphics)
Wayland display manager
Destkop tweak - font scaled to 250%
MC info
MC version - 33.0.61
MC skin - Black on Black
MC size - 150%
Any suggestions or additional info desired?
