Can you provide more details? What platform are you running on? Which shader are you using? Does it happen with all shaders? In theory simple scaling shaders work on separate frames so there is no reason for such behavior. More advanced shaders like CRT simulation may produce described behavior (some might be shader specific, some might be caused by the limited shader support in RP).

Sorry, not had time to properly put together a fully tested response but I'm using one of the libreelec images which is slightly outdated now on a wyse 5070 thin client and I can only say for certain if affected all the crt style shaders, didn't test the lcd type ones when I last had time to check. Hopefully I'll have time in the next week or so to update to latest test image and I'll check behaviour on all included shaders.

Edit:
On further testing I get the following shaders not working in some form or another:
CRT Geom - Flickering sprites not displayed correctly.
CRT glow lancoz - Screen is solid blue
CRT lottes multipass - Screen is solid black
CRT hylian - flickering sprites not displayed correctly
PAL - Screen is solid black.
AdvCartoon - Screen is solid black.
