Calibre doesn't seem to support 125% scaling
Background & Settings
I'm using windows 10 and I have two monitors with different resolutions and scaling:
Problem All Calibre windows (main window, viewer, editor, preferences, etc.) show different scales on two monitors, larger on the 150% scaling screen, and smaller on the 125% scaling screen. Possible reason I made some experiments and found that Calibre doesn't support 125% scaling factor, as it treats a 125% screen same as 100%. Suggestion I'm propose a new feature, making Calibre support 125% scaling factor, in a future release. |

calibre doesnt do scaling, Qt the graphics toolkit calibre uses does. You will need to add support for it there, not in calibre.

Switching between Paged mode and Flow mode is not possible via either Settings nor via shortcut (ctrl+m) when Windows scaling is 150%. On 125% scaling everything is fine.
Monitor 2560x1440, Calibre 7.8, Win10 Guess that's not a QT bug but a bug in calibre itself then. |

Also with external 2560x1440 16″ USB-C/HDMI screen on Linux Mint on Laptop or Raspberry Pi4b Ubuntu the Calibre is fine.

Odd. I'm using a Thinkpad connected to it's internal display and an external display both with 125% scaling and I'm seeing no issues (the internal is using the Intel driver, the external uses the NVidia driver).

As a last resort, I suggest disabling Qt scaling and see if that helps
see https://www.mobileread.com/forums/sh...d.php?t=348475 and https://www.mobileread.com/forums/sh...d.php?t=351959 |

Today I stumbled upon this option in MultiCommander file manager. Not sure if it is open-source and if this setting can be implemented in Calibre, since Calibre is cross-platform and depends on Qt:
(also, can't tell if this option would address the OP's issue) Last edited by Comfy.n; 06-13-2024 at 07:11 PM. |
