Text is rendered incorrectly when using 200% scale

[vdmit]

Flameshot Version

$ flameshot --version
Flameshot v11.0.0 (11.0.0-2 Debian)
Compiled with Qt 5.15.2

Installation Type

Linux, MacOS, or Windows Package manager (apt, pacman, eopkg, choco, brew, ...)

Operating System type and version

Ubuntu 22.04.3 LTS

Description

I have a laptop plus standalone display with different scaling on each screen. Laptop has 1x scale, and 4k external display with 2x scale (200%). I prefer single-display mode.

When I start flameshot on laptop with disconnected display, all works fine, BUT when I connect it to display and switch to it, Flameshot renders texts incorrectly (texts could "fly away" from frame). And, vice versa, if I start flameshot in 200% mode and then switch to internal display, texts also will be mis-positioned.

I've found a simple workaround: just restart flameshot after monitor connection/disconnection, but this is boring.

Steps to reproduce

1. configure 2-monitor mode with different screen scale and single-display mode (e.g. 100% and 200%)
2. start flameshot
3. change screen scale (e.g. by connecting /disconnecting external display)
4. take a screenshot and try to draw some text
5. After switching to another tool (or screen saving) text will be misplaced: to the left if scale has increased, and to the right if scale decreased.

Screenshots or screen recordings

Good screen: Bad screen after display switching:

I can confirm this is a problem. Same thing happens for me at 200%.

• Flameshot 12.1.0
• Xorg (no wayland)
• Arch Linux, gnome version 45.

Although, oddly enough, I recompiled it from source and the problem seems to have gone away. Strange.

Same for me on Windows 10. Restarting Flameshot works.

It happens for me often. I think the reason "reinstalling" fixed it temporarily was that it was because it restarted.
