https://bugs.kde.org/show_bug.cgi?id=397570 --- Comment #11 from Christopher Knoll --- Note, in the last 'single monitor trace', I used a guide to draw the blue circle as the 'proper circle'..this was not drawn from the tablet, this was drawn by using the ellipse guide. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=397570 --- Comment #10 from Christopher Knoll --- Created attachment 114588 --> https://bugs.kde.org/attachment.cgi?id=114588&action=edit Single monitor, full tablet area This is a trace where the tablet properties uses the full tablet space, and only a single monitor is enabled. The distortion between the 'specified dimensions of the tablet' seems to be the same as using the full tablet space. So I don't think the tablet properties is at issue here. Rather it is the 'total screen resolution' that is available on the desktop interfering with how the coordinates of the tablet are being interpreted. -- You are receiving this mail because: You are watching all bug changes.

I've submitted this test trying to make the table area in proportion to the screen resolution. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=397570 --- Comment #8 from Christopher Knoll --- @Boudewijn Rempt : could you clarify: is that the type of table that let's you draw directly on the screen? Because I can imagine that it's a 1:1 mapping between the screen drawing surface and the image presented in Krita. I'm looking for specific examples from people of it working with the type of tablet that's just a drawing tablet (not a monitor/screen interface), where the coordinates of the 'pad' need some translation between the dimensions of the tablet and the dimensions of the external monitor. I think in the cases where the 'pad' is the actual screen, it's 1:1 and no complicated transform is required. In the cases of things like the Wacom Intuos tablet, maybe a transform is required. When I go into the tablet properties, there's really no way I can get a 1:1 ratio between screen resoltuion (in pixels) and tablet coordinates (which they describe as 'Counts'(?!?). I don't know how many 'Counts' go into a 'Pixel'...but the default full size of the tablet is 9500 'Counts' by 15200 'Counts'. I can try an experiment that i have a ratio of 1920/1080 (1.778) on the tablet to see how that will work. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=397570 --- Comment #6 from Christopher Knoll --- Would it be possible for someone to post a screenshot of their own tablets where you are able to trace a coin on their tablet (like a Wacom Intuos tablet) to reproduce this issue? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=397570 --- Comment #5 from Christopher Knoll --- I'm not seeing it in Adobe Sketchbook. It is definitely receiving pen input because it responds to pressure of the pen. This is definitely a problem in some subsystem of Krita. As I explained in my screenshots, the calibration is working properly in other apps. It could very well be how Krita is interpreting the coordinates passed on by the tablet, but Krita's interpretation is wrong, and it seems to be based on the maximum viewable area of the desktop (ie: multi monitors and the native resolution of a single monitor of 1920x1080 shows the issue. I've adjusted (via the tablet properties) the visible portion of the 'capture area' on the screen and on the tablet, and Krita is just reading the information wrong. -- You are receiving this mail because: You are watching all bug changes.

Did not have an impact on how the circle-trace was recieved. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=397570 Bug ID: 397570 Summary: Error in tablet aspect ratio causing traced circles to draw as elipses Product: krita Version: 4.1.1 Platform: MS Windows OS: MS Windows Status: UNCONFIRMED Severity: minor Priority: NOR Component: OpenGL Canvas Assignee: krita-bugs-n...@kde.org Reporter: chriskn...@verizon.net Target Milestone: --- Created attachment 114471 --> https://bugs.kde.org/attachment.cgi?id=114471&action=edit Tracing a Nickel in Krita 4.1.1 On windows 10, 2 monitor setup: 1920x1080 + 1280x1024. Tablet: Wacom Intuos tablet, latest drivers are installed. App version: Krita 4.1.1 Issue: Using a quarter as a trace template, when tracing the circle on a tablet, the circle comes across as an ellipse instead of tracing a circle. It is less exaggerated when disabling one monitor and launching the app on 1 monitor. Have changed preferences on the tablet to custom draw area size, custom monitor display area, with and without windows INK. MS Paint and Adobe Sketchbook do not exhibit this issue, although I understand it's not actually a bug if Krita works differently than another app, or if the app does soemthing unexpected (I expected to trace a circle, but it actually traced an ellipse). It does not seem to make a difference between what document template that is used (Ie: A6 or a custom resolution with some arbitrary DPI does not seem to change the behavior). Attaching images for Krita 4.1.1, MSPaint and Adobe Sketchbook to see the different effects. -- You are receiving this mail because: You are watching all bug changes.
