Because of scaling problems on HighDPI displays the following problems occur:

Selection doesn't match cursor location
Must use minimum Screen scaling settings
No auto scroll happens when content exceeds screen height #301
Content hidden when it exceeds the screen width

If one sets QT_SCALE_FACTOR to 0.5 everything works, but the settings menu is using the scaling setting as well and appears extremely tiny.

I have a HiDPI screen and on Deepin, I have this issue, but on Linux Mint, not.
Can I somehow help point the differences?

I can confirm I'm not seeing any of the mentioned issues when running Cool-Retro-Term v1.0.1 on macOS 10.13.6, using the internal HiDPI display on a Macbook Pro 15".

Looks like its a bug in QT:
https://bugreports.qt.io/browse/QTBUG-48972

Launching CRT from terminal with following command works on 4K screens (scrolling works):
QT_SCALE_FACTOR=1 cool-retro-term

But I don' know how to launch it with scaling parameter from *.desktop file. Following does not work:

[Desktop Entry]
Comment=Use the command line the old way
Exec=QT_SCALE_FACTOR=1 cool-retro-term
GenericName=Terminal emulator
Icon=cool-retro-term
Name=Cool Retro Term
Categories=System;TerminalEmulator;
StartupNotify=true
Terminal=false
Type=Application
Keywords=shell;prompt;command;commandline;

Any ideas?

I'm on Linux Deepin.
