As soon as I have a moment I'll add the function to the plugin. However, with the imminent release of KDE6 there should be no problems because the Qt6 RAM limitation is correctly implemented in the plugin. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=479612 Mirco Miranda changed: What|Removed |Added CC||mirco...@gmail.com --- Comment #10 from Mirco Miranda --- This patch should help: https://invent.kde.org/frameworks/kimageformats/-/merge_requests/209 If I remember correctly, the thumbnail generator leaves the task of determining the correct format to the plugins (regardless of the extension and mime type). As a result, formats like TGA that do not have a unique signature can result in false positives and the plugin tries to read them. It is not a good thing. To avoid excessive RAM usage, last year I modified the thumnailer with memory checks to prevent the system from threshing. I don't know if it still works though. Also, while writing the patch for the TGA I saw that it uses double the necessary memory. This probably doesn't help either. -- You are receiving this mail because: You are watching all bug changes.

Not sure > that makes sense Yeah, it's not really a TGA file. Actually, quite a few of these MIX archives are detected as TGA files for me in Dolphin, though only one of them used a lot of memory. This false detection happens with all the old Command & Conquer games that use MIX files. The games are freeware and can be downloaded from here for testing: https://cnc-comm.com/ -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=479612 --- Comment #5 from Albert Astals Cid --- I'm not sure there's an actual bug, the header of the file describes an image of 41039 * 63040 in size, and thus lots of memory is needed to load it to memory. You'd have to send us the actual file to confirm if it's a TGA file or not and if not if we could bail earlier. As a side thing, the QImageReader API would probably welcome a function saying "fail if we try to read a file bigger than AxB in size"? -- You are receiving this mail because: You are watching all bug changes.
