Bug ID: 49817
Summary: d3d9: Crashes on invalid opengl context with disabled
csmt in IDirect3DDevice9Ex_CreateOffscreenPlainSurface
Product: Wine
Version: 5.17
Hardware: x86-64
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: directx-d3d
Assignee: wine-bugs at winehq.org
Reporter: piotr.caban at gmail.com
Distribution: ---
Created attachment 68148
--> https://bugs.winehq.org/attachment.cgi?id=68148
test that shows invalid error handling on invalid opengl context
The simplest way to reproduce the crash is (I was only testing it running
32-bit process):
- disable csmt
- run the test with WINEDEBUG=warn+heap (to guarantee the crash)
The test destroys window/hdc used by current gl context. After that it's not
possible to restore previous context in Direct3DCreate9Ex. It also leads to a
crash when deleting "destroyed" context in
IDirect3DDevice9Ex_CreateOffscreenPlainSurface.
