I have had this problem for the last year or so and just hopped around screenshot tools until it stopped doing it with one of them.
I have use spectacle, ksnip, flameshot, and probably a few others.
When I hit the screenshot key, and it generates the temp still image you are using to generate a region screenshot, my whole desktop shifts. Think the whole desktop spread across 4 screens shifts half a screen to the right.
Flameshot:
Ksnip:
Spectacle, which avoid this issue for the longest time:
I havent changed anything graphically and haven’t done any custom theming or anything like that. All I have done is update applications as they are updated and they all do this, though they all do it differently. The applications themselves are all using their default settings. It causes me to believe there is likely something at the OS/Desktop level that is causing this.
Any advice? I constantly take tons of region screenshots daily this makes of very difficult as I have to guess where the underlying area is, because the still image given to take a region screenshot of does not align with the actual desktop you are taking a screenshot of.
Any help would be appreciated.
