Summary	0001490: Freeze when file dialog tries to display overly long tooltip of file type selector on mixed-DPI screens
Description	Prerequisites: Hidden HighResUI setting was enabled by user Screen setup: OpenMPT is positioned on low-DPI screen (1920x1200), to the right is a 4k screen (set to 175% scaling) Apparently known file extensions must be shown in Explorer according to https://stackoverflow.com/questions/5732907/hide-extensions-in-vista-windows-7-wpf-filedialog-filter When hovering the file type dropdown in the Open File dialog, OpenMPT will simply freeze. Looking at the stack trace, Windows ends up in an infinite loop in its tooltip handling code due to the overly long "All Modules" filter string. The same happens if "Other Formats" is chosen from the dropdown.

Has the bug occurred in previous versions?
Tested code revision (in case you know it)

Saga Musix 2021-08-28 20:54 administrator ~0004846	Worked around in r15587 (trunk) / r15588 (1.29) by shortening the displayed strings.
