i forgot something: sometimes if you open new tabs (not reproduceable for me) selecting works like it should. Then I have to reopen Firefox to reproduce it.

can you attach the screenshot?

I can reproduce this bug, but I don't understand what happens.

This is a regression of bug 357637. Now, we are using double cache that is gfxTextRunCache and local cache of gfxPangoTextRun (gfxPangoTextRun::mSegments). These caches are not cleared at changing the spacing. But this bug is not important and the patch conflicts to the patch of new textframe. Roc: Will you use the local cache in gfxPangoTextRun? If you don't cache it, the bug will be WFMed by your patch.

My patch should fix this, yeah. Spacing isn't cached in the textrun with my patch.

This bug is fixed by the roc's new textrun. -> FIXED
