I'm using AstroPixelProcessor for stacking at 4800 dpi at first. Didn't know this causes dirty files....I guess the problem was caused by zip compressing in exoirt setting in Photo - curious: I never changed the setting. Tx for help

Yes, correct. This was the problem before. It works again. I guess it was the display driver.

Hello walt.farrell, thanks for answer and helping. No I didn´t change the export settings at first. Tried then without compressing (as Zip) and it was displayed in windows viewer again. Then I read about changing the GPU driver and tried out - and it worked again for other software. I found a broken file, but it´s about 156Mb (export settings were 32bit, but the proberties say 96bit). But anyway there is the same odd thing about webp files. After export into webp it changes darker in Windows. Well, I know, I´m using a very old system, but it´s still working well till now. AMD FX(tm)-8320 Eight-Core Processor at 3.50 GHz, 16Gb RAM, GPU Nvidia Geforce GT730 (guess that´s the problem), Win 10 Home. Thanks! SN2023ixf-M101.tiff

Hello, first of all, I have to say this is not my favorite language. Pls be patient....after updating Affinity Photo 2.1.0 to 2.1.1 unfortunately tiff files won´t be displayd in windows preview and other software isn´t able to open the file any more. I can´t solve the problem. In Version 2.1.0 there wasn´t any problem to export the picture. Tx for help
