https://bugs.kde.org/show_bug.cgi?id=502047 --- Comment #29 from Nate Graham --- Jonas, your issue involves overlapping screens, unlike most other people encountering the bug. This makes it something different, which would need a separate bug report. However overlapping screens like that are not really supported; I'd strongly recommend using a different arrangement, as you'll find a million weird random-feeling bugs everywhere. Also, in a future Plasma version, arrangements like this will be disallowed. -- You are receiving this mail because: You are watching all bug changes.

It doesn't seem like you can solve the issue by fixing the math, but just to prevent double work/research: I already tried reproducing the bug on various scaling factors, writing down which caused the issue, then trying to recreate the formula using all combinations of ceil, floor, round, *2, /2, /scaling_factor up to a depth of five (e.g. `floor(round((width*2)/scaling_factor)/2)`). I wasn't able to make a formula with a +1 pixel error on exactly all the monitor resolutions and scaling factors where the issue occurs. So I think the formula might be way more complicated that just rounding once or twice. (In reply to Nate Graham from comment #29) > Jonas, your issue involves overlapping screens, unlike most other people > encountering the bug. This makes it something different, which would need a > separate bug report. Just to clarify: My day-to-day monitor setup doesn't (purposefully) include overlapping monitors. I simply observed that the screenshot of my leftmost monitor was 1 pixel wider that what the resolution of the monitor supposedly was, which could potentially point at the monitors somehow accidentally overlapping by one pixel. Since most of you had issues reproducing the bug, purposefully overlapping the monitors was only to see if I could forcefully reproduce with any setup and if it would act in the same way as the bug this issue is tackling (which could also be useful for testing a fix). The fact that it does, suggests that my theory of the monitors overlapping with one pixel is correct. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=502047 --- Comment #26 from Noah Davis --- (In reply to Jonas Ryssel from comment #18) > I have a strong suspicion that sometimes KWin and Spectacle disagree on the > resolution of displays when using fractional scaling. That could be the case. I was recently told by KWin a developer that it's actually impossible to properly get the device pixel ratio on Wayland using Qt or KDE APIs. Most of the time QScreen::devicePixelRatio is good enough, but there are edge cases. > With my setup (where the bug is present) `the display is set to 2560x2880 > with 150% scaling. > If I take a full screen screenshot using the "current screen" option in > spectacle, the resolution is 2561x1440. > This suggests that spectacle (or QT or something else) thinks that the > display is 1 pixel wider than what KWin thinks, and if I then place that > display to the left, the displays will overlap by 1 pixel, causing the issue. The screenshot for this case actually comes directly from KWin's screenshot plugin without modification, so I'm not totally sure what's going on there. I think 2560 is likely being divided by 1.5 somewhere (1706.67) and rounded (1707), then multiplied by 1.5 by Spectacle (2560.5) and rounded again (2561). Unfortunately there's not a lot that can be done about that since screen and window sizes are defined in logical coordinates (physical pixel size divided by DPR) as integers. Qt's QScreen and QWindow classes use integers for sizes and positions, but Wayland itself even uses integers for sizes and positions in logical coordinates. This means some precision is guaranteed to be lost. > My (unqualified) guess on what causes the issue / what to look for in > the code > I think there are two bugs which would fix this issue, and I don't know > which one is easier to fix (probably nr. 1). > > 1. There is a math issue somewhere in the code (duh!). > In my tests the issue only seems to be present when `resolution/scaling > factor` calculation results in the fractional part being above .5 (i.e. it > would be rounded up), which suggests a rounding error...

I have two displays side by side (display scaling 118,75% if matters, most likely not). When I try to take a screenshot of whole screen, it presents me panorama of boths screens shown on main display. When I select area on that "combined" screen and confirm, then it returns to normal display (every screen on its own) but **then** takes the screenshot and try to crop according to area I selected. But as it is after combined screen is gone, the offset is wrong (I got [Laptop][Display] while "Display" is my main and is huge resolution. So on "screnshot" "laptop" is inserted on the left side, and shifts the "Display" screen "laptop"'s width to the right. So final crop in my case, if target area was on "Display" is shifted by "Laptop"'s screen width. -- You are receiving this mail because: You are watching all bug changes.

I think I have figured out the root cause... or something close to it. How to forcibly recreate the issue on any PC 1. Have a setup with 2 (or more) displays. 2. In the "display configuration" settings place your displays so that they are overlapping, and with one of them being larger than the other/sticking out to a side. Using display scaling to make one display much larger than the other is an easy way to make them stick out. 3. Open the rectangular region select in spectacle, and select an area which is only shown on one display (i.e. in the part that is sticking out). I've had success based on which part of which display is sticking out, and if I select an area to the top/bottom/left/right of the inner display. So if it doesn't work, swap which display is large and which is small. (See the attached picture, if my explanation isn't clear. The red rectangle is the area that I try to take a screenshot of.) Why it happens (seemingly) randomly I have a strong suspicion that sometimes KWin and Spectacle disagree on the resolution of displays when using fractional scaling. With my setup (where the bug is present) `the display is set to 2560x2880 with 150% scaling. If I take a full screen screenshot using the "current screen" option in spectacle, the resolution is 2561x1440. This suggests that spectacle (or QT or something else) thinks that the display is 1 pixel wider than what KWin thinks, and if I then place that display to the left, the displays will overlap by 1 pixel, causing the issue. My (unqualified) guess on what causes the issue / what to look for in the code I think there are two bugs which would fix this issue, and I don't know which one is easier to fix (probably nr. 1). 1. There is a math issue somewhere in the code (duh!). In my tests the issue only seems to be present when `resolution/scaling factor` calculation results in the fractional part being above .5 (i.e. it would be rounded up), which suggests a rounding error... I have however also found a case where the faction is above .5 and the bug isn't present, so it is only a hunch. I guess this relates to how "weird" resolutions causes the issue. I have another PC setup where I couldn't reproduce the issue, but once I switched to a 1368x768 resolution, it became much easier to reproduce it without purposefully overlapping the displays. 2. If you have overlapping displays, Spectacle seemingly takes your mouse offset relative to the top left corner of one display, then selects an area with the same offset but relative to the other display's top left corner.

https://bugs.kde.org/show_bug.cgi?id=502047 --- Comment #17 from TraceyC --- Thanks for the screen shot of your display setup. Can you attach that directly to the bug report? That way it won't be lost even if the link goes dead. -- You are receiving this mail because: You are watching all bug changes.
