There appearss to be a coordinate conversion problem with the latest code: the x-coordinate is negative when used on some screens...
I've got a new multi-head bug I have not seen before... I've been casually using a 3-screen multi-head setup with xournal for about 4 years, it's worked fine, until a recent upgrade to Ubunut 140.04/ linux mint rebecca. Currently Xournal only works on the left-most screen; nothing is drawn when used on the middle and right screens. However, data is saved: I do get a "save" prompt, and when saving, a file is generated. On loading the file, nothing is displayed.
Looking at the file contents (after ungzipping) shows that the x-coordinate is negative(!) -- deleting the negative sign, and reloading the file does cause the artwork to display (although not in the correct location).
Conclusion: something, somewhere is performing incorrect math on a multi-head setup. FWIW, it is a 3-head setup, and the rightmost heads is rotated, so the total display area is L-shaped, not rectangular.
I have not seen this bug with other drawing programs. I did not see this bug with earlier versions (on ubuntu 12.04) |
