    Cannot scroll in Cool-Retro-Term installed from Deepin Store.Neither with mouse or keyboard.
    Once the output reaches the edge of the screen, you can't scroll eitherway.

    Can you tell me your configurations? I can scroll without any problem.



    Anyways, searching in Cool Retro Term's GitHub's issues page, I've found that the app has some problems with hidpi scaling, more on MacOS laptops, so, on settings > terminal try changing the scaling value to another ones like 75%, 50% or the one you like most, and check if mouse becomes usable again. Greetings.

    I'm too on hidpi screen.
    My scaling in CRT is set to 25%.
    If I scale it back to 50% and more and then scale it back to 25% I can see the rest of the output, but as soon new data fills the screen, the problem comes back.
    I have to upscale and downscale the CRT again to see the whole output.
    Funny thing is, CRT on the same machine, but diferent distro (Mint) works without any problems.

    Probably, hidpi problem is something in common between Deepin and Mac haha... Strange to say too, for me it works well, even using different themes and templates, sorry if I can't find a solution here. You can try to ask the devs (of CRT) on GitHub to see if they put some attention on its integration with Deepin, maybe a package is needed.

    OK, 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):
    1. QT_SCALE_FACTOR=1 cool-retro-term
    Copy the Code


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

    1. [Desktop Entry]
    2. Comment=Use the command line the old way
    3. Exec=QT_SCALE_FACTOR=1 cool-retro-term
    4. GenericName=Terminal emulator
    5. Icon=cool-retro-term
    6. Name=Cool Retro Term
    7. Categories=System;TerminalEmulator;
    8. StartupNotify=true
    9. Terminal=false
    10. Type=Application
    11. Keywords=shell;prompt;command;commandline;
    Copy the Code


    Any ideas?

    As a temporal workaround I've created a simple bash script:
    1. #!/bin/sh
    2. QT_SCALE_FACTOR=1 cool-retro-term
    Copy the Code


    And pointed to it in *desktop file:
    1. [Desktop Entry]
    2. Comment=Use the command line the old way
    3. Exec=home/your_user/path/to/the/script.sh
    4. GenericName=Terminal emulator
    5. Icon=cool-retro-term
    6. Name=Cool Retro Term
    7. Categories=System;TerminalEmulator;
    8. StartupNotify=true
    9. Terminal=false
    10. Type=Application
    11. Keywords=shell;prompt;command;commandline;
    Copy the Code


    This launches the CRT in scaled mode, but I'm curious why it does not work like in the previous post.
