If I set a name filter for QFileDialog that looks like:
"RAW Files (*.cr2 *.cr3 *.crw *.nef *.mrw *.orf *.raf *.pef *.x3f *.dcr *.kdc *.srf *.arw *.raw *.dng *.ia *.rw2)"
on Windows and macOS I am shown (e.g.) files with extensions of .cr2 and .CR2
On Linux Ubuntu 24.04.3 (Noble Numbat) and Linux Mint (which uses Thunar) I am only shown files with extensions .cr2.
On Lubuntu (which uses PCmanFM-Qt file manager) I am shown files with both .cr2 and .CR2 extensions.
Should I expect this level on inconsistency between the different Linux systems?
Do I really need to specify (e.g. for .raf files) .raf, .RAF, .Raf, .rAf, .raF, etc. etc.)
Thanks, David
