--- Comment #9 from sondre.husevold@tietoevry.com --- Comment on attachment 77266 --> https://bugs.winehq.org/attachment.cgi?id=77266 dib trace of proprietary application for 5924ab4c515 regression
Our proprietary application also crashes due to this commit (5924ab4c515). By opening any internal "browse" MDI window the application will promptly crash due to an assert in win32u/dibdrv/objects.c:812 in the function solid_pen_lines.
Reverting the commit 5924ab4c515 on the latest HEAD will resolve the issue and make the application work properly again.
If this is not related to this issue, I can make another bug report. Or if you need a more detailed log I can flesh out the details.
