I can't replicate this on Windows 10 with Qt 6.7.0 (maybe I'm missing something). I tried 1.2x zoom at 100%, 125%, 150% scale and 1.0x zoom at 100%, 125%, 150% scale with default font settings.

monitor configuration of my friend with this issue (after they updated to v2.5.2)

Display 1 (secondary): 4K monitor @ 60Hz in vertical mode with 150% scaling
Display 2 (primary): 1080p monitor @ 60Hz with 100% scaling

both monitors are connected to a rx 6700 xt

the tabs are scrunched on display 1 but not display 2.

if display 1 is switched to 100% scaling, the problem is resolved (but they want to keep 150% scaling).

if both displays are at 150% scaling (and chatterino is restarted), the problem is not resolved.

if display 1 is switched to horizontal mode, the problem is not resolved.

changing the font and zoom settings within chatterino also does not resolve the issue

I... can't reproduce this. From the screenshots in #5798, this looks more like a general scale-change bug. A step-by-step reproduction would be great. Ideally, from a point where the scaling works fine (as that's what it does for me).

Please test this on a fresh portable version (without an account). Then we can be sure the settings are the same.

Same issue here after updating.
Display 1: (primary) 2k Monitor @ 120hz with 100% scaling -> no issues
Display 2: (secondary) 4K Monitor @60Hz with 150% scaling -> tabs are scrunched
if Display 2 is switched to 100%, its fine. Switching it back to 150% immediately makes the issue appear.
When dragging chatterino between the displays its immediately fixed and broken again based on the display.
No changes made to configs directly before or after upgrade.

Note: Also happens in usercard

I think I found the issue in #5802 - at least it worked for Zonian in chat.

It would be great if some of you could test the fix. You can try the PR from that branch by downloading chatterino-windows-x86-64-Qt-6.7.1.zip from https://github.com/Chatterino/chatterino2/actions/runs/12659090287?pr=5802 (direct download link: https://github.com/Chatterino/chatterino2/actions/runs/12659090287/artifacts/2398109983).

This is essentially a nightly build. You can extract it into any folder and run the chatterino.exe from there. It will use your global settings by default. If you don't want that, add portable on a new line in the modes file next to chatterino.exe (open it with notepad or your favourite editor).

Sadly does not fix it for me, WIndows 11, 4k Screen, 150% scaling. still works on 2K screen, 100% scaling
