Bug ID: 59034 Summary: Client area of CLM Explorer main window is rendered completely black on startup Product: Wine Version: 10.19 Hardware: x86-64 URL: https://www.tmsware.com/SetupCLME.exe OS: Linux Status: NEW Keywords: download, regression Severity: normal Priority: P2 Component: win32u Assignee: wine-bugs@list.winehq.org Reporter: arethusa26@gmail.com CC: pgofman@codeweavers.com Regression SHA1: 8d7de32cd646f3d1f118836e643e6146c9837278 Distribution: Fedora
Created attachment 79782 --> http://bugs.winehq.org/attachment.cgi?id=79782 CLM Explorer debug output
With wine-10.19, after starting CLM Explorer, the client area of the main window appears to be completely black. To work around this issue, I had to explicitly minimize the window and then restore it. This problem did not occur with wine-10.10.
Regression testing identified the following commit:
8d7de32cd646f3d1f118836e643e6146c9837278 is the first bad commit commit 8d7de32cd646f3d1f118836e643e6146c9837278 (HEAD) Author: Paul Gofman pgofman@codeweavers.com Date: Tue Jun 24 20:29:28 2025 -0600
win32u: Respect STARTF_USESHOWWINDOW in show_window().
I also observed an issue that may be related. If I try to take a screenshot of the main window with incorrect rendering by requesting the Spectacle tool to capture the active window, I get the following error:
An error occurred while taking a screenshot. KWin screenshot request failed: Invalid window requested Potentially relevant information: - Method: CaptureActiveWindow - Method specific arguments: QMap(("include-decoration", QVariant(bool, true))("include-shadow", QVariant(bool, true))("native-resolution", QVariant(bool, true)))
Also, when running CLM Explorer with a virtual desktop enabled, I notice that the main window starts in a minimized state. I have to restore it in the virtual desktop to interact with it.
