UPDATE 29/04: The bug affecting the in-body image stabilization (IBIS) system of the Canon EOS R5 and Canon EOS R6 looks set to be fixed by an imminent firmware update.
Although Canon has not made an official announcement, it is said to be aware of the issue and will release the update as soon as possible.
According to the Canon Rumors website, there have now been multiple reports of users experiencing blurry images on the Canon EOS R5 and Canon EOS R6 but the company is working on a firmware update to correct the behavior.
No date has been set for the roll-out of any firmware update, but with the number of Canon EOS R5 and Canon EOS R6 users experiencing this issue growing, we can't imagine it will take Canon long to fix the problem.

ORIGINAL STORY: One Canon EOS R5 user has highlighted a possible glitch in the camera's in-body image stabilization (IBIS) system. The result, when IBIS was switched to 'always on', was that the first in a sequence of images was, ironically, blurry.
The photographer first noticed the bug after installing firmware version 1.2.0 on the Canon EOS R5, and it persisted with later versions 1.3.0 and 1.3.1. The issue occurred while using both Canon EF and RF lenses with no image stabilization, the sensor apparently twisting after the first shot.

However, the user noted that if the shutter continued to be half-pressed while in single or continuous autofocus mode, subsequent images were unaffected. You can see the phenomenon for yourself in the video below.
On taking the R5 to a Canon repair centre in Hong Kong the user said they noticed the same issue on cameras displayed there too. Now other Canon EOS R5 users, as well as those of the Canon EOS R6, are also reportedly experiencing the glitch while using the IBIS 'always on' mode.
The EOS R5 and R6 are Canon's first cameras with 5-axis IBIS which, the company claims, can deliver "an industry-leading 8 stops of IS when paired with certain lenses", allowing them to be used handheld in situations that would otherwise require a tripod to produce sharp images. Canon maintains that the IBIS system can produce sharp images during exposures as long as four seconds.
According to Canon Rumors, Canon's technical team is currently investigating the issue. If you are experiencing similar problems, you can report it to your local Canon dealer.
