Why did you pick 999c79863c574bdf3e1650a1b0901fdf83a9e0b4? 5a4b275a201bfc653a99e8b6ab546573553b79ad on its own is not enough?

No need to add me when I'm already engaging.

Unfortunately, the answer from Qt upstream could well be "no paying customer, use latest Qt (6) version instead.

999c79863c574bdf3e1650a1b0901fdf83a9e0b4 is just needed to make the real patch apply seamlessly.

True. But at least we tried to notify them. Maybe we are lucky?


PS: Thank you for engaging :-)

Wanna undo the filelight workaround on your system and try with new patch to qtcore (just linked in See-also) again?

:-) checked it works perfect and confirmed (upstream)

Comment 7 Jaak Ristioja 2023-01-03 08:48:05 UTC

I can also confirm that the qtcore patch alone works. Thanks! :)
