I've been having some trouble with my RollerCoaster Tycoon 3 script. I've been planning to clean it up a lot (native d3dx9 doesn't even seem to be necessary) but there's a problem that remains: fonts. I originally got RCT3 working on Debian 7 "Wheezy." I was using the Catalyst driver for the (old) Radeon HD 3200. However, with an update to Debian 8 "Jessie," I could no longer use Catalyst since it only supported Linux 3.2 and some versions older than that. While RCT3 still runs, ever since I was forced to get rid of Catalyst, the fonts are usually completely mangled, like this (I am now on Kubuntu 15.10):

If I'm lucky, and maybe after a simulated windows reboot or so, I'll get partially-correct fonts, like this:

Sometimes, everything will be completely perfect, but most of the time it's not. I've tried using Wine 1.7.48-WGL-ShareList, based on the WineHQ bug report here, but it seems to have no effect whatsoever.
Is this a familiar problem? Does anyone know of a solution?
Thanks,
