GNOME Bugzilla – Bug 593525
Tablet cursor position is offset when creating first new image
Last modified: 2012-04-20 04:34:10 UTC
How to reproduce this bug: 1) start gimp, or close all current images 2) use your tablet pen and hover over the empty main image window 3) while the pen is still in proximity of the tablet, hit Ctrl+N to create a new image 4) the cursor position of the tablet will now be offset, until you move the pen outside of the window and move it back in, OR you move the mouse.
can you give more info? OS? More details?, i cannot reproduce this with my bamboo pen tablet.
I am running Gimp 2.6.7 on WinXP Pro SP2. I have a bamboo wacom tablet. When I create a new image with ctrl+n (without touching the mouse) while holding the pen over the tablet so that the cursor is in the window area, the little cursor circle (where the paint is going to go) is then not centered correctly to where the windows cursor is, it is offset (it looks like, by the size of the ruler bars on the side of the window). So when you draw like this, you get offset lines. This goes away if the window is moved, or if I exit the window with the tablet and reenter, or if I move the mouse.
I see your trouble, confirmed under Windows Vista OS, more testing under Linux needs to be done. The issue seems to happen also when creating a new image using the menu on top, even the ruler points the cursor in the wrong position, fixes in my case, by just moving out the cursor outside the GIMP windows, menus or using the mouse. Thanks for the info.
could some developer mark it as confirmed? and please look after it?
If this bother you, feel free to provide a patch. Personally I have more important things to work on and I suspect that's how the other core devs reasons too.
Something very similar to this is now happening with GIMP 2.6.8 running in Lucid RC.
Confirmed on Windows 7 Pro, Using Genius Mouse & Pen 12x9 tablet and the last drivers. Actually from what I saw around the forums and I've confirmed myself what is going on is GIMP is registering a negative value on the X axis on some tablets. It looks like a GIMP - generic driver incompatibility. I'm no coder but I believe the easier workaround would be add a checkbox to switch the signal received on the X position if this problem occours. Mods please update.
(In reply to comment #7) Sorry my bad. GIMP versions that were used on the test: v2.6.6 and v2.6.10
Please try GIMP 2.7.4 and report back, we won't fix 2.6 bugs any longer.
Could you please try to reproduce problem with GIMP 2.7.4 or later version and update the bug report with your findings, tia.
Please feel free to reopen this bug if the problem still occurs with a newer version of GIMP.
