Ok, it looks like I'm very close to find it. It's still a little random when it appears, but it has to do with the performance/quality settings. It seems that since the latest update the rendering setting "bilinear" causes problems on my system. Switching bilinear to nearest neighbour makes it sharper. But by far not as sharp and clear as it used to be in the past. I've already installed the latest version of my graphic card drivers and it didn't change. Any other ideas how to solve it?

Yeah guys, I'm sorry... It was the wrong track. It's really weird. Today I opened a picture which had a blurred bg-layer and worked on the post processing layers for around an hour. At the end I've double-checked the bg layer and it was sharp again. I've to keep an eye on it. Maybe it's just some visualisation fault.

Hello together I'm running Affinity Photo 1.10.4.1198 on a Windows 10 PC. Most of the time I'm using TIF files due to export from LR. Sometimes I had the problem that my background layer (which I always kept clean with ctrl + J in the beginning) was blurred/unsharp in my final TIF files. It seemed to be random. But today I found out that if I press 0 (accidentially instead of ctrl + 0), the BG layer was blurred after. There was nothing visible in protocols/history that I activated some kind of filter or something similar. Even with UNDO it won't get back to sharp again. I've also tried to save the file before hitting 0 and then closing without saving. Same result. Next time I've opened the file, the BG layer was unsharp. Anyone else had this issue?

Hello Michail, Thank you for your Ideas. I did a few tests to verify if the filesize can be the cause or not. It seems that really the filesize is the main cause of the problem. I've tested many times with the same results with the following procedure: 1. Create a File with several layers. Export to TIFF. 2. Close the temporary File, reopen the TIFF. 3.a) If TIFF-size is below 2 GB I can open it again and again. No problems --> Add one more layer. b) If TIFF-size is above 2 GB I can't open it with Affinity, but with all other programs named in the thread-opening. After research of the TIFF-specs I found this description on Wikipedia which indicates that issues with 2 GB TIFF Files are known:

Hello together After doing a file stack of two panoramic pictures (one foreground / one background), both TIF, I made an Export to TIFF. After that I closed the programm and reopened it for all the following work. I spend a lot of time on different layers and did also save the Layers in the TIFF-File. Then I closed the huge (2.5GB) File. Now the File can be viewed in Lightroom, IrfanView, Windows Picture Viewer, ... All these are working. But Affinity Photo can't reopen the File. Message "Failed to open TIFF File File type is not supportetd." How can it be, the File was created with Affinity? Is there a File size limit? Any other ideas? System: Windows 10 Home 64bit Affinity Photo Version 1.7.3.481 I need your help. It's ok to do this File again if necessary, but I don't want to spend again that much time with the same result. Thx in advance Manuel
