Do you have multiple monitors or screen scaling?

@DamirPorobic no single monitor
2k Dell S3220DGF

i have 2 monitors but usually only 1 enabled. same issue. it stretches the screen.

OP pleasefix the title grammar to "stretched"(

I was not able to reproduce this issue on my machine but I just pushed a fix for another issue #844 that affects the same component. Can you give it a try if it fixes your issue?

Pushed another fix, please test.

I will need to install the development version and compile?

@bahtioraliev you can use the AppImage, no installation required. https://github.com/ksnip/ksnip/releases/tag/continuous

This fix fixed the preview bug on my pc where pictures would get stretched if i switched to 1 display from 2, and 2 screens on one monitor, if i switched from 1 screen to 2 screens while ksnip was running.
This fix fixed it for me.

@bahtioraliev download AppImage from continuous build section, then go into that folder, open terminal, enter first: chmod a+x ksnip-1.10.0-continuous-x86_64.AppImage, and then a new command ./ksnip-1.10.0-continuous-x86_64.AppImage. This will open up a terminal with a temporary session with ksnip running, and the debug information will be visible on a terminal window.

It's working fine, but my issue appear only once the app starts during startup.

hmm, you can replace the binary used for the startup with the AppImage. Do you know how you configured the startup? Usually it needs a path to a binary, just change it but remember what it was before so you can revert it if required.

Default startup application software in popOS, which run
/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=ksnip org.ksnip.ksnip

yeah, that line, try to replace it with /home/dporobic/downloads/ksnip-1.10.0-continuous-x86_64.AppImage or what ever the path to the AppImage is. Aftewards you can revert it and get the fix with the next minor release.

It's working well from boot, thank you.
Waiting for GA version.

Thanks for checking!
