Hi. I am trialing your program. I like it!
I am struggling with two bugs though, which are common enough to where I can not reliably use the program.
Bug 1) Brush strokes sometimes do not work. I do not understand the condition, but in a blank project, I’d say maybe 1 in every 50 brush strokes do not function? Sometimes it seems like it is happening a lot, several times in a row. Other times, it lets me draw a lot of brush strokes before occurring again. I think there is different wrong behaviors whether you are in a Vector or Raster layer and/or whether you have the Stabilizer enabled or disabled. Having Raw Input enabled or disabled appears to make no difference. Issues occur still with Stabilizer Catch up enabled or disabled. Both wrong behaviors make drawing unreliable.
Behavior 1) This failed brush stroke will result in a dot at the beginning of the stroke, and the rest of the line does not draw. Behavior 2) This failed brush stroke will result in a straight line from the beginning of the brush stroke, to the very end of the brush stroke, regardless of where you move the brush in between those two points.
When the Stabilizer is enabled, and also using the Stabilizer Line as a preview, this draws a white line to where the pen is currently pressed down onto the tablet, even if the brush stroke is still at the place where the pen was placed down onto the tablet. With the Stabilizer disabled, the same issue occurs but the Stabilizer Line does not draw.
Bug 2) In Vector mode exclusively, sometimes overlapping brush strokes will erase the brushes underneath. This happens commonly (about 50% of the time for me) by just drawing a brush stroke with a different color on top of another. *I have much more rarely also had new brush strokes sometimes inheriting the color of the brush stroke they are drawing over (I’ve only seen this in b556). Notable, on the Brush Stroke count, this not increase the counter, so it does seem to be erasing or replacing the line underneath.
Almost (see *) all these behaviors happen to me on b556, b557 and b558.
I have been on Umoupen versions b556, b557 and b558. I am using Windows 11. I am using a Huion KAMVAS 16 GS1562, on latest official drivers. The issue seems to occur regardless of Windows Ink being enabled or disabled. I have 32GB RAM, an RTX 2060 gpu, and a Ryzen 5 9600X cpu.
