SUMMARY The guide lines for the painting assistants also show when tools other then the free hand tool is selected. For some of these tools they also leave behind artifact when the tool is used. Feature request: hide the guidelines for tools other than the free hand tool. STEPS TO REPRODUCE 1. Create an assistant 2. Select a 'ink pen too' 3. draw OBSERVED RESULT Artifacts are show and guide lines are shown EXPECTED RESULT No Artifacts are show and no guide lines are shown SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Are you sure you mean the 4.3.0-beta2 version? When you say 'guidelines', do you mean the Assistant Previews? I've tried this with the latest 5.0.0 prealpha appimage and I don't see artifacts when using the Line, Polygon and Polyline tool with assistant previews turned on. Also, I find the assistant previews to be useful, especially when using the line tool. In Steps To Reproduce, Step 3, which tool do you mean to draw with? Can you provide a screenshot showing the artifacts?
Created attachment 130129 [details] Artifacts (red) while drawing in blue with calligraphy tool
For the screenshit I added four parallel painting assistants. Chose a red color from them. Then selected a blue color and drew with the calligraphy tool (so that is the tool for step 3) While drawing little red lines appear. When releasing the left mouse button longer red lines appear. They disapear when another tool is selected. Might be a minor problem as it only only occurs when in the Display Settings the Canvas Acceleration is turned off. (Had turned it off by accident while working on a unit test).
Thanks for your comment! Automatically switching the status of this bug to REPORTED so that the KDE team knows that the bug is ready to get confirmed. In the future you may also do this yourself when providing needed information.
I see this happen and it only happens with the calligraphy tool when graphics acceleration is turned off and with assistant previews turned on. The long lived artifacts are in the shape and colour of the assistant preview lines. The artifacts are also removed if you scroll-zoom on the screen. [The calligraphy tool does seem to be different/special in various ways.] There are other bugs associated with graphics acceleration being turned off, eg: https://bugs.kde.org/show_bug.cgi?id=423840 and: https://bugs.kde.org/show_bug.cgi?id=424037 These have fix commits being implemented so I suggest waiting until they're available as builds so this can be checked again. Setting to Confirmed and waiting for more tests.
