Images flashing red! Please help!
Anyone know what causes these red borders flashing randomly? Some PNG/image clips on the timeline keep randomly blinking red, like when media is missing. But the files are not actually missing, because the preview still plays correctly.
The weird part is that when a clip blinks red, the effect controls panel also glitches: Transform and other effects for that clip appear/disappear as if Kdenlive is losing the clip state and then restoring it.
I tried clearing the current project cache, including audio/video thumbnails, but it did not change anything. Timeline preview and proxy clips are both 0 B. Reloading/relinking the image sometimes fixes it temporarily, but then the blinking comes back randomly.
Has anyone seen this before? Is this a known bug with still images/PNG clips, Transform effects, or project/media cache?
I'm on Ubuntu 24.04 and Kdenlive 26.04.2 (app image)
PS I can render the project just fine as though nothing is wrong!
