Yes, the problem was reproducible - an attempt to create a texture in a wrong format. According to my colleague it was related to your project, not to Gamestudio. But he planned to look closer into the matter in the next time for identifying the texture in question - he'll contact you when he has found it.

Thank you for the response and the e-mail, I've responded with an updated main file as requested.

With the help of the support (thanks a lot!) I was able to find the reason for the DirectX crash and fix the corresponding code. The issue was as follows:



Calling my_font_update() would not result in an immediate crash but let my_text have an invalid font pointer which would lead to erroneous behavior on subsequent video_... calls.

mean one...

But this is considered to be a bug not you fault, isn't it?

A mean one indeed but I don't think this could be considered an engine bug (because the stuff probably only gets delegated to DirectX, here with an invalid pointer). Instead I think this should be mentioned somewhere and somehow in the manual, for example on the ptr_remove page.
