[Bug 59232] New: Flight Simulator 2000 has flickers and performance issues when rendering the 3D world with a 2D instrument panel in windowed mode
by WineHQ Bugzilla Feb. 20, 2026

Feb. 20, 2026

http://bugs.winehq.org/show_bug.cgi?id=59232 Bug ID: 59232 Summary: Flight Simulator 2000 has flickers and performance issues when rendering the 3D world with a 2D instrument panel in windowed mode Product: Wine Version: 11.0-rc5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: winehq(a)mrpowergamerbr.com Distribution: --- When playing Flight Simulator 2000 has flickers and performance issues when rendering the 3D world with a 2D instrument panel This regression has a bit of history because there are multiple regressions that happened: 1. Versions before e5e2fd0a5209b0d07233d294e0ace5f1e41dfed5 work fine 2. After that commit, the game was rendering a pure black 3D view when playing in "windowed" mode 3. Between e5e2fd0a5209b0d07233d294e0ace5f1e41dfed5 and now, there was a change that made the game actually render "correctly", but with a lot of flickers and performance issues. (I haven't had the time to bisect what commit fixed the black screen and started causing the flickers and performance issues) One curious thing that I found is that, when playing the game in full screen in older Wine versions, even versions that does not contain the regression, if you put the game in fullscreen the game renders, albeit when using the default view (the one with the 2D instrument panel) it has the same slow downs that are present in the newer Wine versions when playing in windowed mode with the default view. So maybe the code path is related? There is also a maybe related regression, where the game also does not work in full screen in newer versions. Here's a video demonstrating the issue, first running it with Wine 10.10, then running with Wine 11.0-rc5: https://youtu.be/pd8FQgbpM8s The game does not work with any of the graphic wrappers I've tested (D7VK and dxwrapper). Attention: When testing FS2000 via Wine, you must set the Windows version to Windows 2000, if you don't, the game will crash with an assertion error! -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 54610] New: fusion:asmcache - 32-bit calls to InstallAssembly(..., NULL) crash on Windows

https://bugs.winehq.org/show_bug.cgi?id=54610 Bug ID: 54610 Summary: fusion:asmcache - 32-bit calls to InstallAssembly(..., NULL) crash on Windows Product: Wine Version: unspecified Hardware: x86-64 OS: Windows Status: NEW Severity: normal Priority: P2 Component: fusion Assignee: wine-bugs(a)winehq.org Reporter: fgouget(a)codeweavers.com fusion:asmcache - 32-bit calls to InstallAssembly(..., NULL) crash on Windows: asmcache.c:846: this is the last test seen before the exception 19e4:asmcache: unhandled exception c0000005 at 0095C478 See https://test.winehq.org/data/patterns.html#fusion:asmcache The crash only happens in the 32-bit w11pro64 tests which represents 100% of the cases where the test actually runs: * The only VM that has the needed fusion dll is w11pro64. * The dll was installed by running the dotnetfx-1.1.exe installer [1] which is only available in 32-bit format. Thus only the 32-bit dll is available and the 64-bit test is skipped. The crash happens in the following call: hr = IAssemblyCache_InstallAssembly(cache, 0, L"wine.dll", NULL); But skipping this call just moves the crash to the next InstallAssembly() call. It's not clear whether the crash is caused by the NULL RefData pointer: the crash still happens if I pass a non-NULL but pretty empty FUSION_INSTALL_REFERENCE structure (in particular szNonCannonicalData == NULL).

This bug has been reported to upstream here: https://github.com/doitsujin/dxvk/issues/5477 Likewise, it seems like it's possible that the crashes that I'm seeing are related to this commit here: https://bugs.winehq.org/show_bug.cgi?id=58143 The behavior that I'm seeing is as follows: Working: Wine 11.0 (with Wayland) with the latest DXVK commits Working: Wine 11.1 (without Wayland) with the latest DXVK commits Broken: Wine 11.1 (with Wayland) with the latest DXVK commits To trigger the bug with 100% certainty, within the game you need to open the player map and use the scroll wheel to zoom in and out. This will reliably cause the game to instantly crash. My system information: Arch Linux (updated as of Jan 27th, 2026) AMD Radeon 7900XT Mesa 25.3.4 (RADV) GNOME 49.3 (Wayland session) 3440x1440 165Hz monitor with VRR enabled Bottles 61.1 (Flathub) Wine 11.1 (Kronek) DXVK Dev Releases (Found here: https://github.com/doitsujin/dxvk/actions/workflows/artifacts.yml?query=bra…) Guild Wars 2 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
