During editing in Pages (or Word) I am getting these glitches (see attachment). Started after the last update to Mac OS 26.3 (beta) Also removed 2 recent instalments (Blackhole audio driver and kDrive/Infomaniak, but trouble is still there.

27" iMac 2020 (Intel) i7 3,8 Ghz AMD Radeon Pro 5500 XT 8 GB 24 GB RAM macOS Tahoe 26.3 (=beta)

Tried restart in safe mode, checked fonts. Talked to aissistent to get a solution, but no ...)

Thx for any advice, Pieter (not a developer so please kee pit simple 🙏🏻)

Since this question isn't about a specific API and it is about some Apple application programs I recommend filing a bug report and switching back to using a non-beta system software release where this problem does not exist.

Normally this is the sort of question you'd ask in the Apple Support Community (Though, I realize questions about beta releases are often referred from there to these developer forums).

Already did that (feedback assistent Apple), but that isn't offering help. I guess I have to wait for a new update, but I will consider leaving the beta programme. These glitches are crippling and therefor super annoying. 'Switching back' is quite an op.
