Vertical lines are appearing randomly.  Moving a window off screen and back will produce them.  Typing in a test area and then hitting Backspace will also produce them.

Reproducible: Always




Probably came in with either of these:

Confirming this behavior.

Scrolling will fix it.

Setting to new, I see the same when editing text in a text box and using the backspace key to erase, light gray vertical lines apppear.  

In fact, you don't even have to type any letters, space off the cursor several spaces from the left edge and use the backspace key - lines will appear.

Tested using latest hourly build, Win7 X64

I suspect this is somehow related to 555353. More specifically this is most likely the CombineWithGeometry bug that is also responsible for a number of other problems. This particular case can probably be fixed relatively easily. Investigating.

I get this issue a lot when scrolling on googlecode pages.
Example: http://code.google.com/p/pcsx2/source/detail?r=3187
(scroll down until the bar on the left starts to move along with the visible area)

Confirmed :)

We know the cause of this, we're working on a 'proper' fix in conjunction with the fixes for anti-aliased clipping.

It appears https://bugzilla.mozilla.org/show_bug.cgi?id=567295 has fixed this problem, at least om my end.

I no longer can see the vertical lines either using the latest hourly build.

Same here.  No vertical lines when using the backspace while editing textboxes.

This is indeed fixed by bug 567295.
