This problem occurs the same on all of my computers, Dell 1501 laptop, Intel DG35EC & DG31GL motherboards. All with up-to-date Ubuntu 9.04.
I made a fresh install on the DG31GL, thinking that the problem would go away. It persists on the new install.
This problem started at some point after upgrading to 9.04. It was not apparent in 8.10.
Start QCAD, open Application preferences dialog, drag mouse pointer over check box text. The check box text area becomes blacked out.
Line width on layer 0 is set to .25mm.
Draw some lines intersecting or not.
Zoom in to screen width less than 1.7 inches.
Lines start to disappear. The more you zoom in, the more lines disappear.
Yes, the lines are still in the center of the screen.
They appear temporarily when the mouse pointer is moved over them.
Anyone else have this problem?
Anyone know how to fix it?
